Why birth time matters in your Vedic birth chart
What changes when a birth time is exact, approximate or unknown, and how to avoid false precision in a kundli reading.
Use the local clock time
Enter the time recorded where the person was born. The place supplies the time zone. Historical time-zone changes and daylight saving can matter. A clock time can occasionally occur twice or not occur at all. The app asks for clarification when the time cannot be resolved safely.
Some parts change quickly
The rising sign, houses and divisional charts depend on birth time. Small time changes near a boundary can change a placement used in an interpretation. This is why an exact-looking chart does not prove that an uncertain input was correct.
An unknown time is still unknown
If a time is missing, a noon reference can help show limited calculations. Noon is a reference, not a discovered birth time. Even a Moon sign or nakshatra may be uncertain near a boundary. MyAstroChat marks unknown times and limits the conclusions it draws.
Do not manufacture precision
A chart cannot prove that a family estimate was exact. Compare a birth record with the time entered, and keep approximate times marked as approximate. Do not change the input only to obtain a more flattering reading. If a corrected input changes an earlier result, the explanation should say what changed.
Before asking about timing
Confirm the birth date, clock time, place and whether the time is exact. Then inspect the period dates returned by the calculation. A precise dasha date is a computed boundary in a traditional system. It is not proof that a job, wedding or other event will happen on that date.
