How to use it
- Countdown: pick a date to see how many days and weekends are left. Past dates show as days since.
- Anniversaries: enter a start date to list the 100th, 200th, 1000th day and yearly anniversaries.
- Days between: count calendar days, weeks and weekdays between two dates, useful for contracts and leave.
- Add days: find the date N days after or before any date, with its weekday.
In Korea, couples and parents count the first day as day 1, so the "100th day" is 99 days after the start. Untick "Count the first day as day 1" to count from zero instead.
FAQ
Does "days between" include the end date?
No. It counts the days from the start date up to the end date, the usual convention. Add one if you need both days included.
Are holidays excluded from weekdays?
Weekdays exclude Saturdays and Sundays only. Public holidays are not removed.
Is my countdown saved?
Your last dates are kept in this browser so they are there when you return.
