Nashta Jataka - Unknown Birth Time Estimator
Frequently asked questions about Nashta Jataka
What is Nashta Jataka?
Lost horoscopy: the birth date and place are known, but the clock is not. Lagna still walks through all twelve signs that day, so this page gives a working estimate - solar noon, or the mid-point of a remembered part of day - plus the lagna bands for that date. It is a sketch to study, not a recovered minute.
Is the estimated time my real birth time?
No. Noon is a conventional stand-in when nothing of the hour survives. A remembered morning or evening only narrows Lagna to a few signs. A hospital note, a family clock and a full reading still come first. For a personalised review use Ask an astrologer.
Why solar noon when I know nothing?
Because some clock must be chosen to draw houses, and local solar noon sits in the middle of the civil day. Slow grahas on that date barely move. The Moon may change rashi once; the page says so when it does. Treating noon as proven Lagna is the mistake this helper is written to avoid.
How is this different from Birth Time Rectification Helper?
This page starts from no clock. The Birth Time Rectification Helper needs a scan window you already trust and dated life events, then ranks D1 and Navamsa bands inside that window. Use Nashta Jataka first; switch to rectification when a two- or three-hour range appears.
What can I trust in the chart without a time?
Sun sign and the slow grahas (Jupiter, Saturn, Rahu, Ketu) on that date. Moon sign is often stable unless it changes rashi that day. Lagna, house numbers, Navamsa lagna and dasha of a fast graha are not. Janma Rashi still helps when the Moon does not flip. A full D1 belongs in Kundli Maker only as a working sketch.
Does birth place still matter?
Yes. Lagna, sunrise and solar noon are local. Pick the city from the dropdown so coordinates are right. At very high latitudes sunrise can fail; the page then uses 06:00 and 18:00 for day-parts and says so. The Moon's longitude at a given instant is the same worldwide.
About Nashta Jataka
Nashta Jataka is the classical name for a lost horoscope: the birth date and place are known, but the clock is not. Lagna moves about one sign every two hours, so a full day still holds all twelve rising signs. What this page does is give a working estimate you can study, not a recovered minute. When nothing of the hour is remembered, the stand-in is local solar noon. If you recall morning, evening or another part of day, the mid-point of that stretch is used instead.
The Moon, Sun and slow grahas on that date are the parts of the chart that usually survive an unknown time. House numbers, Navamsa lagna and anything timed to Lagna do not. This is not event-based rectification - that lives on the Birth Time Rectification Helper once you have even a short window and dated events. It is also not a second Kundli Maker, and not KP ruling-planet work.
Pick the city from the dropdown so sunrise, noon and Lagna use the right coordinates. A hospital or family record, if one turns up later, still comes first. Editorial pages are reviewed by Astro Arpita Nath. Results are free to share or save as a PDF.
