Your exact age in years, months and days, the days you’ve lived and how long until your birthday.
How it works
Age is counted in full years, then months and days since the last birthday. If you were born on 29 February, in non-leap years your birthday is taken as 1 March.
Change the reference date to see how old someone was or will be on a particular day.
