How it works
Each date on the board counts calendar days from today, the way a calendar does: tomorrow is 1 day away, and the number drops by one at midnight where you are. Today isn't counted and the day itself is, which is also how timeanddate.com and calculator.net count by default, and why the number of days equals the number of sleeps. Because it counts dates rather than hours, a clock change can't make it a day off.
Add a time and, on the day itself, the board counts down the hours and then the minutes. Times are your local time. A date can repeat every year; a birthday on February 29 falls on February 28 in other years.
A one-off date that has passed counts up for a week, then moves to Earlier. Nothing is deleted unless you remove it. Your board is saved in this browser only. A share link holds one date's name, date and, if set, time and time zone, and nothing else.
Questions people ask
- How are the days counted?
- The board counts calendar days from today to the date, so tomorrow is 1 day away and the number drops by one at midnight. That is also the default in timeanddate's and calculator.net's day counters, which leave the end date out unless you ask for it.
- Is a sleep the same as a day?
- Yes: the number of nights before a date equals the number of calendar days to it, so 3 days to go means 3 sleeps.
- What happens when a date passes?
- It counts up under Just passed for 7 days, then moves to Earlier, where you can still see or remove it. A date set to repeat every year shows next year's date the day after.
- Does a shared countdown show the same number to everyone?
- It counts to the same calendar date, so the number matches wherever it is the same day and can differ by one where it isn't yet. If you add a time, the link carries your time zone, so a friend elsewhere sees that moment in their own time.
