How this exact age calculator works
Age is usually expressed as completed years, followed by the months and days since your most recent birthday. The calculator uses calendar dates rather than an average number of days per month.
Completed years
Years increase only on your birthday, not on 1 January or after a fixed number of days.
Months and days
Month lengths vary, so the remaining months and days are calculated against the actual calendar.
Next birthday
The countdown shows the number of full calendar days remaining until your next birthday.
