Every tool runs entirely in your browser. Your files are never uploaded to a server.
Enter a target date and the day you are counting from, and the remaining days appear along with weeks, working days and the weekday it falls on. Dates already past are counted forward instead.
How to use the Days Until Calculator
- Enter the target date. A deadline, a holiday, a birthday — anything with a fixed date.
- Set the day you are counting from. It defaults to when this page was updated. Change it to today.
- Read the countdown. Days remaining, the same span in calendar terms, working days, and the weekday it lands on.
About counting down to a date
Countdowns look like simple subtraction, and the day count genuinely is — but the moment you want the same span expressed as "two months and three days" the calendar reasserts itself, because months have no fixed length. Both are shown here for that reason. The other thing worth deciding deliberately is whether today counts. This calculator measures from the start of one day to the start of another, so a date tomorrow is one day away and today is zero. Some countdowns use inclusive counting instead, where today is day one, which produces an answer larger by exactly one and is the usual source of off-by-one confusion between two people looking at the same deadline. Working days are offered because most real deadlines are business deadlines, but they exclude weekends only. Public holidays vary by country and by year, and quietly assuming a set of them would make the number wrong for most visitors, so the honest thing is to leave that subtraction to you. Everything is computed in UTC in your browser.
