Frequently asked questions
Does this account for leap years?+
Yes, all calculations use exact calendar dates, including leap years.
Calculating exact age gets fiddly once you account for varying month lengths and leap years, which is where manual counting usually goes wrong. This tool handles the calendar math precisely, breaking down age into years, months, and days, and also shows a running total of days and weeks lived — a fun way to see how many days old someone actually is, along with an exact countdown to their next birthday.
