The age is counted on the calendar, the same way as in the date difference calculator: full years first, then full months, then the days left over. Total days are the days from the date of birth to the chosen date, total weeks are those days ÷ 7 rounded down, and total months are the full months.
The next birthday is the first one on or after the chosen date, and the countdown is the days until it. Someone born on 29 February has a birthday on 1 March in years without a 29 February, the first day the full year is counted.
Worked example
Someone born on May 15, 1990 is 36 years, 5 months and 6 days old on October 21, 2026. That is 437 full months, 1,901 full weeks or 13,308 days. Their next birthday, on May 15, 2027, is 206 days away, when they turn 37.
