Vedic Birthday
Janma Tithi
Your true birthday in the Vedic calendar is your Janma Tithi — the day each year when the same tithi recurs in the same lunar month (māsa) as your birth. Because it follows the Moon, it falls on a different civil date each year. Enter your birth details to find it, computed with Lāhirī (sidereal) ayanāṃśa — the same engine as the Pañcāṅga.

Dates are computed by the sunrise-prevailing-tithi convention and may differ by a day from regional pañcāṅgas that use a different vyāpti rule.
About the Janma Tithi
In the Vedic tradition the birthday observed is the tithi (lunar day) of birth within its lunar month — not the Gregorian date. Many families mark it with a special pūjā, abhiṣeka or recitation on this day.
Because the lunar year is about eleven days shorter than the solar year (corrected by an extra month, the adhika māsa, every few years), your Vedic birthday shifts against the civil calendar from year to year.
