Count the days between two dates — useful for deadlines, holidays, notice periods, project timelines or counting down to an event. Pick a start and end date and the calculator shows the gap in days, weeks and approximate months. It ignores the order of the dates, so it always gives a positive count.

Frequently asked questions
Does it include both dates?
It counts the number of days from the start date to the end date. Add one if you need to include both the first and last day in your total.
Does it account for leap years?
Yes. It works directly from the calendar dates, so leap years and different month lengths are handled automatically.
