Birth Time Rectification Method

There are various birth time rectification and verification techniques available in Vedic astrology texts. In this post, I want to talk about a simple technique suggested by Kalidas in Uttar Kalamrit. In fact, there are three techniques suggested in Uttar Kalamrit as follows 1. Nakshatra Shuddhi, for finding out the Nakshatra (constellation) 2. Man - Woman Janma Shuddhi, for finding out the sex 3. Lagna Shuddhi, for finding out the Lagna (ascendant) I am planning to have one post for each technique. Here is the first technique 1. Nakshatra Shuddhi Multiply the Ghatikas and Vighatikas of the Ishta Kala by 4 and divide the product by 9. The reminder should be counted beginning with Ashwini, Magha or Moola in whatsoever Paryaya it falls. The 27 Nakshatras are distributed in 3 Paryayas consisting of 1st to 9th, 10th to 18th and 19th to 27th. This will give the Janma Nakshatra. Example: Suppose the native was born on 6.3.1980 at Ishta Ghatika 56.12,. Therefore, 54.12 X 4 /9 = 224.48 / 9 = 24 X 9 + 8.48. As the reminder is 8.48, Nakshatra may be Ashlesha (9th Nakshatra), Jyeshtha (18th Nakshatra) or Revati (27th Nakshatra). You might be wondering what is the Ishtakal and how to calculate it. Istakaal is the difference between sunrise and time of birth. Please note that the time of birth should be converted to local mean time before finding out the difference. If you use IST/ standard time, the result will be incorrect. Man -Woman Janma Shuddhi Convert the Ishta Ghatika into Palas (by multiplying Ghatikas with 60). Divide the same by 225. If the reminder is: 0 to 15 - male 16 to 45 - female 46 to 90 - male 91 to 150 - female 151 to 225 - male These five groups represent , in their order male, female, male, female and male respectively. Example: Ishta Ghatikas are 56.12. If we convert it into palas it will be 56 X 60 + 12 = 3372. 3372 / 225 = 14 X 225 + 222. In other words if we divide the ishtakal in palas by 225, the reminder will be 222 which falls into 5th zone. Therefore the birth should be of a male. In case the horoscope that we are using for verification is of a female, we can conclude that the time is not correct and needs some verification. As this technique is based on Ishtakal, we can also use the distance between sun and ascendant for calculating the zone. If you don't know, Sun and Ascendant conjoins around Sunrise and Sun

keeps moving away from ascendant. During sunset, Sun is around 180 degrees from Ascendant or roughly in 7th house. We can convert this formula in degree format for easy application. The third technique is for verifying Lagna (ascendant). Lagna Shuddhi Find out the Rasi occupied by the Moon and Mandi; and their Navamsas. The native will have this birth either in the Rasi occupied by Maandi or the Moon whichever be the stronger; or in the Lagna Rasi which will be the 7th, 5th or the 9th from either of them. If instead of these two Rasis, the Navamsa Rasi owned by Mandi or the Moon be stronger, then the Janma Lagna will be in the stronger Navamsa Rasi or the 7th, 5th or the 9th from it. In other words this method suggests that the lagna of person must always be 1, 5, 7, 9 from either Moon or Mandi. This should be checked both from Lagna chart as well as Navamsa chart. This is a method which suggests that there is a connection between moon position and ascendant position at the time of birth. In KP system there is a popular birth time rectification method which says that the Ascendant sub lord should be the same or connected with star lord of the Moon. I beleive that this KP rectification method also has root in the Kalidas method. Though KP method ignores Mandi and just relies on Ascendant-Moon connection. This is my third and the last post on birth time rectification methods in Uttar Kalamrit. Though Uttar Kalamrit is not the only texts that talks about birth time rectificaiton.
