Countdown Calculator
Count down the days, hours and minutes to any event in your local time.
About the Countdown Calculator
Enter the date of a wedding, exam, launch or holiday, and an optional time, to see exactly how long is left in days, hours and minutes, plus the total in hours and in minutes. If the date has already passed, it shows the time since instead.
The countdown uses your device's clock and time zone, so it accounts for daylight saving changes between now and the event. Change any field, or reload the page, to refresh it.
The formula
Time left = event date-time − now
How to read your result
- Days, hours and minutes are whole units left over after each larger unit, so “51d 3h 20m” means 51 full days plus 3 hours and 20 minutes.
- Total hours and total minutes are the whole span in one unit, handy for planning study or work time.
Worked example
From 1 January 2026 to 25 December 2026
- 25 December is day 359 of the year
- 359 − 1 = 358 days
- That's 51 weeks and 1 day
Things to keep in mind
- Times are in your device's time zone. For an event in another zone, enter its time converted to yours (the Time Zone Converter helps).
- The answer depends on your device clock being correct.
