Free date difference calculator. Find the number of years, months, weeks and days between two dates. Great for deadlines, projects and countdowns.
Enter your values and select Calculate to see the result.
Counting the time between two dates by hand is surprisingly easy to get wrong because months have different lengths and leap years add a day. It comes up in contracts, project plans, countdowns and travel.
Pick a start date and an end date. The calculator shows the gap in years, months and days, the total number of days, and the same gap in weeks. The order of the dates does not matter, and the end date is not counted as an extra day.
