About the Days Between Dates tool
How many days until a deadline, since a birthday, or between two events? Pick two dates and see the gap in days, weeks, weekdays and hours, along with a calendar breakdown in years, months and days.
How to use it
- Pick a start date and an end date.
- Tick “include the end date” if you want both days counted.
- Read the results and copy them if needed.
Frequently asked questions
Should I include the end date?
For “how long between” questions, leave it off (Monday to Tuesday is 1 day). For counting days of an event, include it (a Monday-to-Friday conference is 5 days).
Does it account for leap years?
Yes. Dates are counted on the real calendar, including February 29.
