How the countdown calculator works
Pick a date, and a time if you like. The calculator compares it with your device’s clock and shows the days, hours, minutes and seconds left, updating every second. It also gives the number of calendar days, weeks and weekdays to go.
The method
Time left = target date and time − now
1 day = 86,400 seconds
Worked example
On November 10, 2026 at 15:30:20, the time until New Year’s Day 2027 (midnight on January 1) is 51 days, 8 hours, 29 minutes and 40 seconds: 52 calendar days, or 7 weeks and 3 days.
Frequently asked questions
Which time zone does the countdown use?
Your device’s own clock and time zone. Someone in another time zone counting down to the same date sees a different number of hours, because their midnight comes at a different moment.
What does “weekdays to go” count?
Monday to Friday days from tomorrow up to and including the target date. Public holidays are not taken off; use the Business Days Calculator to exclude them.
Can I count up from a date in the past?
Yes. If the date has passed, the calculator shows how long ago it was.
Why might the hours be off by one?
If the clocks change for daylight saving time before the target date, the real number of hours is one more or less than the wall-clock difference shown.
