Frequently asked questions

Exact age is calculated by counting complete years, then remaining complete months, then remaining days from the last completed month. This accounts for different month lengths and leap years. For example, someone born on 15 March 1990 on 20 August 2025 is 35 years, 5 months, and 5 days old โ€” not just 35.43 years. The calculator above handles all edge cases including leap year birthdays (29 February).
To find how many days old you are, subtract your birth date from today's date. The calculator above shows your total days, weeks, months, and hours. The total days figure can be surprising โ€” a 30-year-old has lived over 10,950 days, and a 40-year-old over 14,600 days.
