Birth Time Rectification (BTR)-1 in Vaidik Astrology
See also Birth Time Rectification in KP System BTR with Kundalee Software
But a majority of astrologers use birth charts with Vinshottaree events for BTR, which yield results that do not provide satisfactory solutions consistently because Vinshottaree Dashaa is foolproof only when DPC is used and if used with birth charts, it may sometimes misguide us , because if the Dashaa Kaarak planet is very strong in DPC and weak in birth chart then DPC will suppress birth chart. Since DPC (Dashaa Pravesh Chart) needs many days of painstaking efforts, SCD is the easiest and accurate tool for BTR.
Traditional methods of BTR are unusable now-a-days because Garbhaadhaan
Sanskaar time and Sootikaa Griha descriptions are not recorded.
No astrology software can give authentic time of birth with a one click. Reaching correct birth time or Rectification (Shuddhi) is an ART, and an astrologer should first be well versed in this art. Rectification is not a name of mathematical formula or table.
Some astrology software has options of rectification, including freeware JHora (like time change in seconds, minute, hour etc). Others, like Parashara Light and SriJyoti Star support more detailed options (like list of events and relevant Dashaa). While western astrology software like Janus and Solar Fire have rich options of direction and progressions along with life events. Even they cannot help you, unless you don't know the basics. So one ought to first determine what kind of rectification, he is looking for.
(1) When both date and time of birth are unknown. This is the most difficult situation, and very difficult to reach even correct Lagna. Only experienced gurus and experts can handle these kinds of cases. Better is to avoid such of horoscopes with uncertain date as well time.
(2) When only date of birth is known, and time is completely unknown. For example people who know date, but don't have any clue of reliable time of birth. In this situation, relying on Moon chart is safe. Guessing incorrect Lagna by just looking face or nature may be misleading. This is again difficult situation to handle, for there are 12 Lagna in a day. But, if you have very vital life trends, or significant events that can match any certain Lagna then go ahead. First determine exact sign of Moon, if it changes sign within given date of birth. Then find the Deccan (Dreshkaan or D-3) of Moon. It means you will now have 1/3 of day, or about 4 Lagna signs as available options. Sometime, born-in-day (diurnal) or born-in-night (nocturnal) nativity approach also proves helpful.
(3) When date and large interval of time is known. For example, a person says, he was born somewhat in morning from 6 am to 12 pm noon. Then you have to choose an ascendant (Lagna) out of about 3 options (that could rise in given interval of 6 am to 12 pm). Make a list of of 10 to 20 very significant life events. Then try to fit/superimpose these events with respect to all available 3 Lagna. Then again, use Bhrigu/Sudarshan Chakra (12-year cycle) to approach correct Lagna same as above. Sometimes, trend of Vinshottaree Mahaa-dashaa may also prove helpful.
(4) When date and small interval of time is known. In this case, often there is a uncertainty between two ascendants. This situation is bit easier than the above situation. For rectification, approach will be the same as above. Using life events with respect to Bhrigu/Sudarshan Chakra (12-year cycle) and Vinshottaree Antar-dashaa.
(5) When date and definite time of birth is known, and only minor degree correction is needed. This is a quite common situation, in which Lagna of Raashi (D-1) is known, but exact divisional charts (Varg Chakra) need to rectify. List a few significant events of life for Rectifying Divisional Charts. It is better to take 4 or 5 events from parental/domestic life for Dwaadashaansh (D-12), 5 events from marital life for Navaansh (D-9), and 5 events from children's life for Saptaansh (D-7). First separately rectify these basic Varg Chakra. Then try to align all under considered Varg.
(6) Whether date, time are correctly known from authentic written record. Despite, birth time needs to rectify to reach exact Naadee Ansh (150th part of a rising sign). This is not easy, unless you are at home with Naadee Ansh and subtle divisions of Tattwa.
For last few decade, KP system has been gained a reliable tool of rectification
of Birth Time with the help of constellation Lord and Sub-lords. Read:
Besides above, prenatal epoch and Nasht Jaatakam are the advance aspects of rectification.
BTR As in Lomash Sanhitaa
Checking the accuracy of Lagna (Lagna Rectification) - Two methods for BT rectification
are discussed below -
1. Use of Gulikaa - Computation of Gulikaa
Here the word ‘Dhruvakaa’ is used as a technical term to refer to these numbers. This is the calculation for Keralite ‘Mandee’ (the mathematical point at the end of a full Muhoort with in the Yam of Saturn) rather than the Paraasharee Gulikaa (the mathematical point at the starting of Saturn’s Yam), which is termed Gulikaa here. The rising time of Gulikaa (Mandee) for all the weekdays along with the same in Hr-Min are tabulated below. Please note that Gulika (Mandi) rises this much time after Sunrise provided the day or night duration is 12 hours exact. If the day or night duration changes the rising time also should be adjusted proportionately.
Weekday Day (Khatika)
Night (Khatika) Day (Hr. Min) Day (Hr. Min)
The above tabulation is for days with 30 Naadikaa (12 hours). When there are increase
or decrease in day and night span, proportionate adjustments should be made in Gulika
rising time as well.
The condition given to ensure whether the lagna is accurate or not is that - If
Lagna is accurate then Gulikaa will come in houses 1st-2nd-7th- 5th-9th-10th to
it only. Or in other words if the Gulikaa is in 3rd-4th-6th- 8th-11th- 12th from
Lagna then it indicates that the given Lagna is inaccurate. But this condition
applies only if the Lagna is strong. Otherwise make the necessary adjustment in
time and move Lagna to the next or previous sign (whichever is near) so that the
above condition would be satisfied. Even though not told here it should be known
that a Lagna becomes strong
The same condition applies to Moon Lagna also when checking whether it is strong or not. So the point to note is that, if as per the above condition if Lagna is not strong but instead Moon sign is strong then correction of Moon sign (and not the Lagna) should be done based on the position of Gulikaa (and all the predictions should be done based on Moon Lagna in this case and not Lagna). Thus if Moon sign is strong then, if Gulikaa is not in 3-4-6-8-11-12 houses from Moon sign, it can be assumed that Moon sign is accurate. If Moon sign is strong and this condition regarding Gulikaa is not satisfied then make the necessary adjustment in time and move Moon sign to the next or previous sign (whichever is nearer) so that the above condition would be satisfied. The proposed position of Gulikaa relative to Lagna for humans and animals in the above quote is tabulated below.
Sl Human/insect/ Aquatic animal
Position of Gulikaa
It is not told whether the Gulikaa should be for the birth of plants etc in the above quote. The above classification seems to be some how connected to the classification of signs as Sthal (Land)-Jal (Aquatic)-Sareesrip a (Reptiles and Insects); less water - in between land and water).
2. Use of Praanapad - Correcting Lagna using Praanapad
Computation of Praanapad
The steps to calculate Praanapad is clarified below.
Praanapad must be in trine to Lagna. If not, make the necessary adjustment in time so that Praanapad falls in trine of Lagna.
Practically speaking, the difference of even a single Vighatee (24 sec) in birth time can cause a difference of 1 sign in Praanapad. And the maximum difference that needs to be made to bring Praanapad to the trine of Lagna is at max 3 Vighatee (1 min 12 sec) difference in given birth time. This is too small a correction and practically useless. Both these methods (one using Gulikaa and the other using Praanapad) are very vague and crude methods which should at the most be used only to check the accuracy of the given birth time, and never to correct it. Numerous other good and authentic birth time rectification methods supported by sages are discussed in the book “Secrets of Birth Time Rectification” (by Sreenadh OG; Sagar Publications).
Even if one gets some perfect Siddhaant without a millisecond of error, one has to carry out birth time rectification of few minutes in most cases. My code resulted in smaller error in birth time which I soon corrected. For instance, correction in Deshaantar (Longitude) due to the change of Ujjain's longitude from the center of old town to exact location of the Mahaakaal Mandir resulted in subtraction of 0.63 seconds in my own birth time. True-Day correction also results in a small correction in Isht Kaal amounting to a few seconds of error in birth time only, small in comparison to few minutes of errors in most natives.
