Free Vedic tool · Birth time lab
Not sure of the exact time?
Give your best guess and how unsure you are. The lab sweeps every 5 minutes across your window, maps exactly what flips and when, and — if you add life events — scores which candidate time fits your Vimshottari dashas best.
Birth details
Life events (optional, up to 3)
Major dated events — marriage, childbirth, new job, relocation — help score candidate times.
How the lab works
The ascendant (Lagna) moves about 1° every 4 minutes, so even a half-hour uncertainty can flip your Lagna sign — while the Moon barely moves. The lab computes a chart every 5 minutes across your window and reports exactly what changes and at what minute. With life events, each candidate time is scored by whether its Vimshottari mahadasha/antardasha at the event date connects to the event's houses and karakas (e.g., the 7th house and Venus for marriage).
This is an exploratory lab, not a jyotishi's rectification — professional birth-time rectification uses prashna and fine event-matching. Use the lab's output as the starting point for that conversation.
