Calculating age for someone born in 2004
Subtract 2004 from the current year, then subtract one if your birthday has not happened yet this year. On your birthday, you complete another year. To find the months and days as well, use your full birth date in the calculator above.
Calendar age and days lived
Calendar months have different lengths, so dividing days by 365 does not give an exact age. This calculator counts completed months and the remaining days, including leap days in your total days lived. Dates stay in your browser and are not saved.
