Frequently Asked Questions

How is exact age calculated?

By subtracting the birth date from the reference date and normalising the result into complete years, then months, then remaining days — accounting for varying month lengths and leap years.

Why does age matter for tax?

Senior citizen (60+) and super senior citizen (80+) status changes the exemption limit under the old regime.

Does this handle leap years?

Yes — the calculation works from real calendar dates, so leap days are accounted for.
