How many days until my birthday?

Pick your birthday. You get the days to go, the weekday it falls on and the age you turn — for your next ten birthdays.

How old will I be…

…in the year …on the date

How the count works

Calendar days, from today where you are. Tomorrow is one day away; on the day itself the answer is "Today". There are no hours or time zones in it.
Age is whole years. You turn 34 on your birthday; the day before, you are 33. Without a birth year there is no age to show, but the countdown and the weekdays still work.
The age you turn in a year is that year minus the year you were born — reached on your birthday, not on 1 January. That is the "How old will I be in 2030?" answer.

How old am I today?

Type your birthday with the year, and the line "Age today" in the result is your age in whole years. To see your age on any other date — an interview, a trip, a cut-off — use the "…on the date" field; it starts on today's date.

How old will I be in 2027?

Find the decade you were born in, then the last digit of the year. The number is the age you turn on your birthday in 2027 — until that day, you are one younger.

Born on 29 February

In a year without 29 February, the birthday — and the new age — is counted on 28 February. Some people celebrate on 1 March instead; this page uses 28 February, and so does Giftwise, which sends its reminder that day. For someone born on 29 February 2000:
