Enter the due date to see exactly how many days are left until the baby is expected.
Pick a valid date to start the countdown.
The countdown is measured from your device's local date today to the due date you choose, in whole days.
How does it work?
Days are counted in whole calendar days using UTC, so the result is unaffected by time zones or daylight saving. A negative count means the date has already passed.
Days-until formula
- d
- Whole days between today and the target date.
- target
- The date you are counting down to.
- today
- The current date (your local today).
From 1 June to 1 July is 30 days.
Method & sources
The count is whole days from today to the due date you enter. The due date is an estimate from your provider; babies rarely arrive exactly on it. A negative count means the due date has already passed.
How we calculate

A note on due dates
A due date is an estimate, usually about 40 weeks from the last period or set by a scan. Only around one in twenty babies arrives exactly on it, so treat the countdown as a guide, not a guarantee. The count itself is in whole calendar days, in UTC, so it never drifts with time zones.
