Zero on the day itself

The countdown runs from today to your next birthday. If today is your birthday it shows zero rather than 365 — the day itself counts as arrived, not as a full year away.

How to count down to your birthday

1 Enter your date of birth.

2 Read the days remaining.

3 The date, weekday and age you will turn are all shown.

4 On the day itself it reads zero.

The zero-on-the-day behaviour is a deliberate choice and not every calculator makes it. Treating the birthday as "already here" matches how people talk — nobody says they have 365 days to wait on their birthday. The alternative, rolling straight to next year, is defensible for a scheduling tool and wrong for a countdown.
