Set a time range
Use an approximate range, or a full-day search if the birth time is completely unknown.
Birth-time rectification
Estimate your birth time from the life events you remember.
If you don’t know your exact birth time, or only have an approximate one, TrueRise helps narrow it down. Add dated life events, and the app returns a likely time with a confidence score and event-by-event evidence. Your data stays on your device. No accounts. No tracking.
How it works
A personal estimate, not a guarantee.
Enter a birth date, birthplace, and an approximate time range. Leave it wide open if the time is unknown. Add a few dated life events. TrueRise returns the most likely time within your range, a confidence score, and a breakdown of how each event shaped the result.
Add life events
Add dated events: moves, relationships, career changes, or other milestones you remember.
Review the result

Birth-time rectification
Why the exact birth time matters for your natal chart.
Your natal chart depends on your birth date, birthplace, and birth time. The time determines your ascendant, the rising sign, which changes roughly every two hours. An uncertain birth time means an uncertain chart. Astrological rectification works backward from dated life events to find the time most consistent with your personal history.
The rising sign depends on exact birth time
The ascendant moves through all twelve signs over the course of a day. A 15–30-minute error in birth time can place the rising sign in a completely different sign.
A time range instead of guessing
TrueRise lets you define a narrow or full-day search range, then identifies the birth time in that range best supported by your life events.
Each event contributes evidence
Dated events carry astrological weight. TrueRise scores each event against each candidate time and returns a breakdown showing which events supported the estimate.
