What each Countdown input means
- Target date
- The date you are counting down to: a holiday, a trip, a deadline, a due date.
- From date (optional)
- The day to count from — today unless you change it. Leave it on today and the count updates itself each day.
Countdown formula
days left = target date − from date (in whole days) · weeks = days ÷ 7 · hours = days × 24
The countdown is the number of midnights between the 'from' date — today unless you change it — and the target. That is the figure most people mean by 'days until': on the day before, it reads 1, and on the day itself 0. It is also shown as weeks and days, and as hours, which suits short countdowns. Because the count works from calendar dates rather than clock time, daylight-saving changes do not shift it, and a 29 February in between is counted like any other day. A target in the past reads as days ago, which turns the page into a 'how long since' counter as well.
Countdown worked example
From Sunday 30 August 2026 to New Year's Day 2027 (a Friday) is 124 days — 17 weeks and 5 days, or 2,976 hours. On 31 December the countdown reads 1.
More Countdown examples
From Friday 2 October to Christmas Day 2026 is 84 days — exactly 12 weeks, or 2,016 hours.
From 2 October to Halloween is 29 days: 4 weeks and 1 day.
Where the Countdown calculator can give the wrong answer
- The count is in whole days and ignores the time of day. At 11 pm the night before, it still says 1.
- Sites that count today as day 1 will show one more; this one does not.
- Leave the 'from' date as today and the countdown changes by itself each day.

Countdown FAQ
- Set the target to 25 December. From 2 October 2026, it is 84 days.
- No. It counts the days still to come, so the day before the event shows 1 and the event itself 0.
- Yes. Set the 'from' date to any day — a booking date, the start of a project — to see how far away the target was from there.
- The page shows weeks and days: 124 days is 17 weeks and 5 days.
- The same number as the days: one night for every midnight between now and the day. 84 days to Christmas is 84 sleeps.
- It counts whole days. For the hours and minutes left on the day itself, use the hours calculator from the time now to the time of the event.
- Set the target to your next birthday. The age calculator also shows the days to your next birthday, alongside your exact age.
