  • Astrology started of as a sibling of Astronomy.
  • Astro means “pertaining to the stars”.
  • There are numerous books and courses on Astrology.
  • Astrology is considered as pseudo-science by some.
  • Astrology is relied heavily by some.
  • Astrology may be studied for profit or for leisure.


There are several flavors of astrology. The list is not exhaustive.

  • Natal Horoscope
    Western, Eastern and variants
  • Pyat tha na Zartar (Ad-hoc query)
  • Maha Bote
  • Sann Bedin
  • Inga Weikkza
  • Predictions based on sun sign
  • Predictions based on moon sign and/or transit
  • Saya Bedin (specializing in Health and Medicine)


  • My beloved father had a decent collection of Bedin books.
  • I learned how to construct a natal horoscope from a sayadaw and found it was very time consuming to do by hand.
  • I learned how to do predictions from another sayadaw (whose specialty was in prescribing protective verses and Yadaya for those who are “Kan Khe”).
  • I had a chance to help the Bedin Community when my childhood friend U Myint Sein (PBRS, Principal of BARB) asked me to help develop some computer programs (for Veda).

Underlying data

  • Some systems require data about the place, date and time of birth. Using a person’s date of birth and the birth place, a natal horoscope can be constructed.
  • Some systems do not expect exact data.
    In the early days, there was no standard practice to record the date and time of a birth. Some old people say, “I was born at ‘soon khan chein’ (time when the monks go on alms)”.
    The date of birth is sufficient to use Maha Bote.
  • A few systems allow relaxations.
    The “day of week” when one was born might be good enough to figure out the characteristics of a person, or whether there is opportunity for business.


  • A Zartar is most commonly a natal horoscope. It is a horoscope constructed for a person using his/her birth details.
  • An Eka Sekka Zartar uses one circle to map out the positions of the Gyohs — in the Geo-centric model — at the time of birth.
    It includes the Lagna (Lett or Ascendant) which represents the “horizon”.
  • The Geo-centric model places the Earth in the center.
  • A Gyoh refers to one of the following :
    Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Rahu, Ketu
  • A Tri Sekka Zartar uses three circles to describe Yathi, Bawa and Nawin.
  • Than Deik Hta Pyeik Ka Dein” and equivalent are tables used for interpolating the position of the Gyohs.
  • Astronomy prefers the Heliocentric model with the Sun in the center.
    In the Heliocentric model, the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Pluto orbit the Sun with elliptical paths.
    The Moon orbits round the Earth.
  • Rahu is known as the Dragon’s Head (or the Northern Node).
  • Ketu is known as the Dragon’s Tail (or the Southern Node).
  • Rahu and Ketu are diametrically opposite in the Zartar.
  • The imaginary line connecting the two Nodes depict the relative placements of the Sun, Earth and the Moon.

Variations in the depiction of a horoscope

  • Use of “Fixed Zodiac” (in the Eastern systems) vs. “Moving Zodiac” (in the Western systems)
  • Use of “Precession of the equinoxes” for conversion between the Fixed Zodiac and Moving Zodiac
  • Method used to determine the Lagna (Ascendant) and the Houses
    e.g. Placidian, Lahiri, KP

U Myint Sein (PBRS, Principal of BARB, GBNF) requested me to help with BARB courses by

  • developing computer programs to construct Zartar (Tri Sekka and beyond)
  • guiding BARB teachers (in charge of “Ganita”) and advanced students the use of programmable calculators and hand held computers (e.g. ZX80)
  • asking selected Computer Science students to study Veda
    (In addition to the BARB courses, there were special “Ah Hor” sessions for friends seeking Veda advice.)
  • Under my supervision, U Win Latt (UCC) implemented WinHoro in BASIC and U Zaw Tun (UCC) implemented a Prolog program to interpret the charts.
  • U Aung Myint Oo (EC84, UCC) implemented WinHoro using C.
  • U Aung Myint (UCC) wrote :
    Done the horoscope (Tre Satka Zartar) with your guidance in 1975 with our first computer ICL.
