How many days until… — count down to any date or yearly event

How to use the days until calculator

1. Type an Event name, such as “Exam” or “Mum’s birthday”. It only labels the result.
2. Set the Event date.
3. Leave Repeats every year (birthday, anniversary, holiday) ticked for annual dates, or untick it for one-off dates such as a deadline or a trip.
4. Count from is filled in with today’s date when the page opens. Change it to see how many days were left on another day.
5. Read the large number for the days left, then the date, the months and days, the weeks and days, the weekdays and the hours.

What it does and when to use it

Students count to exams, families count to holidays, and travellers check how much of a visa or passport is left. The months-and-days line suits notices written in months.

For a ticking clock in hours, minutes and seconds, use the countdown timer. To count days between two dates in the past, use the date difference calculator. To find a date a set number of days away, use add or subtract days.

How it works

Both dates are turned into day numbers and subtracted, so the answer is exact for any dates in years 1 to 9999. With the yearly box ticked, the tool looks for the event’s month and day on or after the Count from date, this year or next. Months and days are counted as whole calendar months first, then leftover days. Hours are days × 24. The tool works with dates only, not clock times, so your time zone cannot add or remove a day. One side effect is that the hours figure ignores daylight-saving changes.

Worked examples

All three use 7 October 2026 as the Count from date.

New Year. Event date 1 January, yearly: 86 days, which is 2 months and 25 days, or 12 weeks and 2 days. That is 2,064 hours and 62 weekdays.

A leap-day birthday. Event date 29 February 2000, yearly. The year 2027 has no 29 February, so the next date shown is Sunday, 28 February 2027, 144 days away.

A visa expiring on 30 June 2028. One-off date: 632 days, or 20 months and 23 days, with 452 weekdays (Mon–Fri) after the count-from date.

Limits and tips

• The weekday count starts after the Count from date; the label says “after today” when that is today, and names the date otherwise.
• If a one-off date has already passed, the tool shows how long ago it was and suggests ticking the yearly box.
• Today’s date is filled in from the UTC calendar, so for a few hours around your local midnight it can be a day off. Check the Count from field if the answer looks one day out.
• The result does not refresh itself at midnight; reload the page or change a field.
• For working days that skip public holidays, use the business days calculator.
