It is not the English date.

Your Vedic birthday does not sit on the same date of the Gregorian calendar every year.

It is the janma tithi.

The tithi is the lunar day you were born on, counted by the Moon's phase.

Same tithi, different date.

Same lunar month, same tithi, but a different Gregorian date each year.

Tamil tradition uses nakshatra.

Instead of the tithi, the birthday is the day the Moon returns to your birth star.

Why it drifts

A lunar year is about 11 days shorter than the English year, so the date moves about 11 days earlier each year, then jumps after an extra month is added.

Festivals follow the same rule.

Janmashtami and Rama Navami are fixed by tithi, which is why their English dates change every year.

Birth details matter.

The date, time and place of birth change the result, because the tithi can change within a day.
