Tibetan Calendar and Astrology 
 
"Our outer world - environment and beings -
Subject to time and the auspicious conjunction of planets and stars,
Our inner being - aggregates and sense bases -
Subject to the movement of subtle channels, winds and essences,
Are in fact the deities of Glorious Kalachakra - the Wheel of Time.
One who knows this should so compose a wondrous calendar...
Such is the delirious chatter of the old man Dilgo Khyentse.'
'A Wondrous Calendar....' By Dilgo Khyentse Rinpoche

 

Introduction

Kalachakra means Time-Wheel, as "Kala" is Sanskrit for Time and "Cakra" (or Chakra) is Wheel in Sanskrit. One could also translate it as Time-Cycles. Much in this tradition revolves around the concept of time and cycles: from the cycles of the planets, to the cycles of our breath and the practice of controlling the most subtle energies within one's body on the path to enlightenment.

The time-cycles in the external universe are interrelated to the inner cycles of energy in our bodies. Thus, the phrase 'as it is outside, so it is within the body' can be found in the Kalachakra Tantra to emphasize similarities between ourselves and the cosmos; the basis for astrology. But the similarities are taken to an even more profound level of connections and interdependence as taught in the Kalachakra literature. Ultimately, the teachings are designed to guide the practitioner on the path to Buddhahood, and the Kalachakra contains its own unique methods which are among the most complicated within Buddhism. However, individual practitioners require require different methods to achieve the same goals.

Based on a mix of Indian, Chinese and Kalachakra Tantra sources, the unique system of the Tibetan calendar and astrology was developed. The system is used in a quite different way from the western astrological approach, where birth-charts form the main basis. It should be noted that the time of birth is generally considered much less important in buddhist thought, for example because the actual new life started at the time of fertilization of the egg, rather than at the moment of birth.

The Kalachakra astrological system forms one of the main building blocks to compose the Tibetan calendar. Part of the first chapter of the Kalachakra Tantra is dedicated to making an accurate calendar. The astrology in the Kalachakra is not unlike the Western system, and complicated calculations are required to determine e.g. the exact location of the planets. The system is so complex, that the traditional Tibetan calculations may require an overhaul, as Edward Henning suggests in his book 'Kalacakra and the Tibetan Calendar.

As with many of the concepts in Kalachakra, much of the basis for eg. astronomy, astrology and time-divisions can be found in the traditional teachings of the Indian Vedas, but the interpretation can be different

Tibetan Astrology

Tibetan Astrology originated from several different traditions: Indian, Chinese, the local Bön religion, and the Buddhist Kalachakra tantra.

Traditionally, astrology was one of the five secondary sciences in Tibet. It concerns not only divination, but it is also used in the study of time cycles, Tibetan chronology and the compilation of the calendar. The calendar in the form of an almanac is still quite important in the daily life of the Tibetans to ensure that their daily activities are in tune with the cosmos.

In general, certain days of the week and of the month are considered auspicious for specific activities (from marriage to hanging of prayer flags - even cutting one's hair); but also, every day relates to one's own specific astrological chart of the day of birth. Furthermore, the position of the planets and the cycles of the elements determine good or bad fortune and good or bad health.

Traditional Tibetan Astrology ChartIn a Tibetan village, the astrologer would use his skills to advise people about nearly everything: from the weather, the best time to harvest, verify if and when two people should marry, to important business deals. In case the outcome would be negative, often religious practices would be advised to remove obstacles, which would be carried out by monks of the local monastery. Traditionally, a doctor in Tibetan medicine (Amchi) has also studied Astrology to determine for example the best timing for a treatment. As a consequence, in many villages, the Tibetan doctor would also be the astrologer; besides a local Buddhist teacher, he/she would probably be the most important person to visit for general advice.

At the birth of a child, the charts would be checked to see if any special rituals were required to ward off negative planetary influences. Also a "death chart" would often be prepared to decide the exact performance of the funeral. Improper performance could result in problems for the family, as well as for the deceased.

Tibetan astrology is not only strongly linked to religion, also Tibetan medical practitioners would study astrology (and religious texts) to determine the timing of medication etc.

Tibetan 'Naktsi' astrology has mainly Chinese origins, and the 'Kartsi' astrology has Indian origins.

TIBETAN 'NAMELESS RELIGION' ORIGIN

From the ancient 'nameless religion' of Tibet, a system is preserved in current Tibetan astrology which relates to Five Individual Forces (La - vitality, Sok - life potential, Lu - bodily health, Wangthang - personal power, and Lungta - wind horse) or energies within a person. These energies relate to the Chinese animals and elements, for example, the La force of the Horse is Wood etc. This system is unique to Tibet and is important to establish yearly horoscopes.

The La moves through the body in a monthly cycle, the Wangthang element is the same element that rules the year in Chinese astrology.

When the forces become weak, numerous specific practices are prescribed to strengthen the force again, from saving lives of animals to reciting mantras or performing special rituals like exorcism.

BÖN ORIGINS

The Bon religion was well established in Tibet before the introduction of Buddhism. Over the centuries however, it appears that many Buddhist practices have taken root in Bon and reverse. For someone not too familiar with robes, iconography or rituals it may even be hard to spot the difference.

Astrology is important within the Bon system. Methods are given for divination, warding off negative influences, astrological calculations and medical diagnosis.

The four types of astrological calculation systems according to David Snellgrove are:

  • The mirror of magical horoscopes
  • The circle of Parkhas (trigrams) and Mewas (magic squares in 9 colours) - Chinese origin
  • The Wheel of Time (Kalachakra) of the Elements
  • The Jushak method: calculation of interdependence

A very important Bon deity is called Balchen Geko, who is said to govern time and the three world of existence. In this respect the deity is analogous to Kalachakra in Buddhism.

The Tibetan system works with a 360-day lunar year and cycles of 60 and 180 years. As a year is longer than 360 days, some days are doubled, but others are skipped in a complicated manner. To make the calendar fit the observations, occasionally even an extra month is introduced.

CHINESE ORIGINS

From Chinese astronomy and astrology originate concepts like the Trigrams from the I Ching, the nine Magic Squares or Mewas, cycles of 12 and 60 years, the twelve Animals, the five elements and the duality of Yin and Yang etc. The traditional explanations say that princess Kongyo introduced Chinese astrology in Tibet in 643, but much earlier influences are very likely.

Two main Tibetan systems are of Chinese origin: 'Naktsi' or 'black astrology' (referring to the Tibetan name for China: 'black area'), and the 'astrology of the elements' or Jungtsi.

Five Elements
The five Chinese elements or agents are Earth, Water, Fire, Wood and Metal; which are different from the elements that constitute the universe in Indian astrology: Earth, Water, Fire, Air and Ether.
The Chinese elements are natural dynamic forces of transformation - energies - and constantly interacting with each other. The names do not directly relate to the objects of the same name, but refer to affinities which can lead to positive, neutral and negative relations. Too much or too little of a specific element can become dangerous. They are related to a direction and a time of year. Earth relates to the periods around the end and start of each season and is related to the intermediate directions (NE, SE, SW, NW). Wood dominates in spring and the East, Fire in summer and the South, Metal in the autumn and the West, Water in the winter and the North.
Each element has a specific relation to an activity, colour, planet, organ etc. The elements have specific relationships with each other, described as Mother, Son, Friend and Enemy. They also can have a feminine or masculine polarity - similar to Yin and Yang.

Twelve Animals
The twelve animals: Rat, Cow,Tiger, Hare, Dragon, Snake, Horse, Sheep, Monkey, Bird, Dog and Pig relate to hours, days, months and years. Each animal is related to an element which represents its life force, a direction, a specific sex and certain personality treats. The animals can go together well or difficult in various levels.

Each year is a combination of an animal and an element. This leads to cycles of 12 x 5 = 60 years. Also, years are alternatingly male or female.

Nine Mewas

The 'nine moles' or 'nine coloured islands' are derived from the I Ching and Chinese numerology. Each of the nine Mewas is related to a colour, a direction and an element. For example, the three whites (1, 6 and 8) are metal. Each day, month and year, the Mewas move.

Eight Trigrams (Parkhas)

These represent the equivalent of the Chinese pa-kua, which form the basis of the I Ching. In turn, the pa-kua are based on the concept of Yin and Yang. They are: Fire, Earth, Metal, Sky, Water, Mountain, Wood and Wind. They are an extension of the theory of the Five Elements.

INDIAN ORIGINS

Tibetan astrology may have been influenced by Indian sources as much as from Chinese. Analogous to above, India was known as the 'white area' and gave rise to the term 'white astrology'.

Early Indian civilisation had much cultural interchange with the outside world, which is reflected in an identical zodiac to the Mesopotamians (twelve signs and twelve houses) and the widespread decans. Later on however, differences occurred for example when most other systems moved away from the early sidereal zodiac, which is preserved in the Indian tradition. Far back in history, also the Chinese and Indian system may have common origins. Similarities are for example the 28 Chinese lunar constellations and the 27 or 28 Indian Naksatras (from the Vedas), and the importance of the lunar nodes, Rahu and Ketu.

Signs of the zodiac
The Indian system is based on the observation of the sun, moon and the planets like Western astrology. The sky at night appears like a globe dotted with stars surrounding the earth. During one year, the sun moves along this expanse of stars and completes one cycle. This cycle is divided in 12 sections, called the signs of the zodiac. Western astrology follows the cycles of the sun related to the seasons, and the Tibeto-Indian system follows the cycles of the sun related to the stars, and there is a small difference between these two. Over the centuries, a difference of almost a complete sign has accumulated. For the rest, the signs are the same as in the Western system: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. The general explanation of the signs is similar to the Western system. Two major differences are the relation to different parts of the body and the fact that Indian signs are divided into day and night signs (indicating when their influence is strongest).

Lunar mansions
Indian astrology mentions 27 lunar mansions (Naksatras), but as one of them comprises two adjacent constellations, it covers 28 constellations. Each of these mansions is related to an Indian element (Wind, Fire, Water, Earth). In the Tibetan system, the lunar mansions have also been connected to the Chinese elements and directions.

Planet orbits around Mount MeruPlanets
Both the signs of the zodiac and the lunar mansions are ruled by a particular planet, in order: Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury. (Ketu and Rahu are nodes of the moon.) The ruling of the planets over the signs is the same as in Western astrology.

 

KALACHAKRA

The Kalachakra tantric system contains not only an extensive religious practice system, but also medical knowledge. At the core of the system is the very familiar concept of 'as above, so below', the correspondence of the outer universe with the inner physical and mental processes in humans. It describes the interaction of human and cosmic phenomena with time and builds a complete system of Indian astrology.
Interestingly enough, this tradition contains all elements of Indian astrology, but merges it with Chinese principles. The Tibetans started to adopt the 60 year cycle in 1027, as it was taught both in the Kalachakra tantra and the Chinese tradition.

About Kalachakra astrology and astronomy, the website Kalacakra.org is probably the best source of information on the web.

BUDDHISM

One could say that almost everything in Tibetan culture is strongly influenced by Buddhism. Even myths have been 'buddhified' over the ages. In Tibet, usually a teacher (lama), either monk or layman, would be the local astrologer. When living in a monastery, he would be responsible for establishing the calendar for religious practices and festivals.

The following legend comes from 'Tibetan Astrology' by Philippe Cornu. It is based on the manifestation of a Buddha called Manjushri (see image), who is a personification of wisdom and insight. Tibetan teachers invoke Manjushri at the commencement of any astrological undertaking.

"At the beginning of the present age or kalpa, while the future universe was still immense chaos, Manjushri caused a giant golden turtle to arise from his own mind, and this turtle emerged from the waters of the primordial ocean. Seeing in a dream that the universe in formation required a stable base, Manjushri pierced the flank of the turtle with a golden arrow. The injured animal turned on its back and sank into the ocean, giving forth blood and excrement, from which there arose the constituent elements of the universe. The created world thenceforth rested on the flat belly of the turtle, upon which Manjushri wrote all the secrets of the times to come in the form of sacred hieroglyphic signs."

As Tibetan astrology is so directly related to religion, it is regarded as a practical method to reduce uncertainty and suffering. The correct motivation of an astrologer is compassion (wanting others to be free from suffering), and as such an astrologer is not different from a spiritual practitioner, a medical doctor or a Buddhist teacher.

 

The Tibetan Calendar

Unlike the modern Western calendar, the Tibetan calendar is based on the cycles of the moon, and various dates are considered especially auspicious or inauspicious for certain practices. The information to collate this page is mainly taken from the sources mentioned at the bottom of this page.
Also some of the most important days of the Theravada tradition are included: over the centuries, a difference of one month has developed with the Tibetan tradition. Edward Henning describes the probable origin of this discrepancy in his book 'Kalacakra and the Tibetan Calendar'.

MISSING AND DOUBLE DAYS

The complicated Tibetan calendar is based on lunar cycles. As the lunar cycle is less than 30 days, and the year is divided into 12 months, tricks are applied to compensate for the difference between the 12 moon cycles in approximately 354 days and the actual 365-something days of the year. For this, sometimes dates appear double or not at all. About every 30 months, like in early 2000, even a complete month was doubled for compensation.
Special days which fall on double days are usually celebrated on the second day, but may be celebrated on the first day if it is more convenient. Special days which fall on missing days are usually celebrated on the preceding day.

FOUR MAJOR FESTIVALS

There are four major Special Buddha days Tibetan Buddhist Festival Day or "Festivals" (düchen) in a year which relate to the life of Buddha Shakyamuni. During these days, it is said that the effects of positive or negative actions are multiplied 100 million times, so practice is strongly advised.
Chotrul Düchen: During the first two weeks of the new year, it is celebrated that the Buddha displayed a miracle each day to increase the merit and devotion of future disciples. During these days, the Gelugpa Mönlam Chenmo (great prayer festival) is celebrated and extra practice is highly advised. The 15th of the 1st month is the "Day of Miracles".
Saga Dawa Düchen: the 15th of the 4th month, Buddha Shakyamuni's Birth, Enlightenment and Parinirvana are celebrated. He was born in Lumbini (current-day Nepal) became enlightened in Bodhgaya (India) and entered parinirvana ("passed away") in Kushinagar (India).
Chökhor Düchen: the 4th of the 6th month, the "First Turning of the Wheel of Dharma" (first teaching) is celebrated. For the first seven weeks after his Enlightenment, Buddha did not teach. Encouraged by Indra and Brahma, he then gave his first teachings at Sarnath on the Four Noble Truths.
Lha Bab Düchen: the 22nd of the 9th month, 'Buddha Shakyamuni's Descent from the Heaven of 33' is celebrated. Buddha's mother had been reborn in Indra's heaven. To repay her kindness and to benefit the gods, Buddha spent three months teaching in the Heaven of 33. This is not as often stated, in Tushita heaven; Tushita is the realm where the Buddha lived before he descended to Earth. Possibly somewhat confusing can be that one week before, on the 15th of the 9th month, it is celebrated that he accepted to return from the Heaven of 33.

In the Theravada tradition the following main full-moon days are observed (information from Urban Dharma):

Magha Puja (‘Sangha Day’)
The Buddha gave the teaching on the basis of the discipline (Ovada Patimokkha) to the spontaneous gathering of 1250 arahants.

Vesakha Puja (Wesak) (‘Buddha Day’)
The birth, enlightenment and passing away of the Buddha.

Asalha Puja (‘Dhamma Day’)
The Buddha’s first discourse, given to the five samanas in the Deer Park at Sarnath, near Varanasi. The traditional Rainy-Season Retreat (Vassa) begins on the next day.

Pavarana Day
This marks the end of the three-month Vassa-retreat. In the following month, lay people may offer the Kathina-robe as part of a general alms-giving ceremony.

SOLAR AND LUNAR ECLIPSES

During a (partial) solar eclipse the effects of positive and negative actions are multiplied by 10,000 according to the Khandro site, 100 million times according to Lama Zopa Rinpoche. During (partial) lunar eclipse, the factor is 7 million according to Lama Zopa Rinpoche, practices like taking the Eight Mahayana Precepts are thus strongly advised.

MONTHLY RECURRING DATES

Every months, certain dates on the lunar calendar have special significance. On the Buddha-daysare said to be multiplied. The significance and advised practices on these days may vary, but here are some examples:
- Tibetan 8th: special day for Medicine Buddha, Tara and/or Mahakala practice and taking Eight Mahayana Precepts
- Tibetan 10th: Guru Rinpoche day: on the 10th of each month, a special occasion in Guru Padmasambhava's life is celebrated. Tsog ritual is advised on this day by everyone who has received a Highest Yoga Tantra initiation, it is specifically related to the "Father tantras"
- Tibetan 15th, full moon: Amitabha Buddha, meditation, recitation of Sutras and taking Eight Mahayana Precepts, Kalachakra day
- Tibetan 25th: Dakini's day: the 25th of every month is related to the "Mother tantras" and tsog is advised for everyone who has received a Highest Yoga Tantra initiation.
- Tibetan 29th: Dharmapala's day (Dharma Protectors): the 29th of every month is a special day for Protector practice.
- Tibetan 30th, new moon: Shakyamuni Buddha meditation, recitation of Sutras and taking Eight Mahayana Precepts

Sojong: on 14 or 15th and 29th or 30th, confession practice for monks and nuns.

SPECIAL MONTHS

Saka Dawa: the 4th month; 100,000 multiplying of positive actions, so practice is emphasized and eating meat or other 'black food' (like any meat, fish, eggs, onions, garlic etc.) is discouraged.
The 11th month is especially associated with the practices of Chakrasamvara and Vajrayogini, which belong to the Mother Tantras. The 25th of this month is an annual special days for these practices.

HANGING PRAYER FLAGS

Generally, Monday is a good day to hang prayer flags and Friday is very good. According to Lama Zopa Rinpoche, by hanging prayer flags (including long prayer flags and banners) on the wrong astrological dates, "you will continuously receive obstacles."
The following are inauspicious dates according to the Tibetan calendar: 10th and 22nd of the First, Fifth and Ninth months; 7th and 19th of the Second, Sixth and Tenth months; 4th and 16th of the Third, Seventh and Eleventh months; 1st and 13th of the Fourth, Eighth and Twelfth months.

TIBETAN BIRTHDAYS

This can be very confusing to non-Tibetans. When a baby is born, one calls it one year old. This is probably connected to the fact that the baby started its rebirth already 9 months earlier at conception. Next, birthdays for ordinary people are normally celebrated once a year, as part of Losar (Tibetan New Year). This means in practice that a baby born on the last day of the Tibetan year is called one year old, and can be called a two-year-old on the next day! So if you need to know accurately how old a Tibetan is, try to find out when he or she was born according to the Western calendar.
The birthdays of great Tibetan saints are usually celebrated on the same date of the Tibetan calendar. Probably to avoid confusion (but also adding to it), the birthday of His Holiness the Dalai Lama is celebrated on a fixed date of the Western calendar: July 6.
