How it works
Enter a date of birth to see your exact age in years, months and days, how many days you have lived, and the date of your next birthday. Change “Age on this date” to find an age at any other date.
- age = whole years, then months, then days since the birth date
- birthday on 29 Feb → 1 Mar in non-leap years
Assumptions
- Dates use the Gregorian calendar and are not affected by time zones or daylight saving.
