How We Calculate Your Age in Days
We calculate the total number of days between your date of birth and today. This includes leap years — every four years has an extra day (February 29), which adds to your total. The calculation uses midnight-to-midnight days based on your local timezone.
For example, someone born on January 1, 1990 has lived through approximately 13,200+ days as of early 2026.
