How Age Is Calculated
Age is computed by comparing your birth date to today's date. The calculator accounts for varying month lengths and leap years to give you a fully accurate breakdown in years, months, and days.
How Many Days Have I Lived?
The calculator also shows your total days lived - every day from your birth date to today, including leap years. The average person lives around 28,000 days; enter your birthday to see exactly where you stand.
How Many Days Until My Next Birthday?
Once you enter your date of birth, the calculator automatically counts the days remaining until your next birthday - so you always know exactly how long to wait (or celebrate).

- Verifying age for legal or official documents
