A date difference calculator can help plan a project, count days to an event or compare two calendar dates. Select both dates and check whether the calculation includes the start date.
How to use Date Difference Calculator
- Choose the start date in the first field.
- Choose the end date in the second field.
- Select Calculate to view the elapsed difference.
- Reverse the dates if you want to check a different interval.
- For deadlines, confirm inclusive-day rules, holidays and time zones with the responsible organization.
Counting days for a deadline
The tool gives the elapsed difference, so it does not count both the first day and the last day. If your rule counts both, add one day. Deadlines may also leave out weekends or public holidays and may depend on a time zone, which this tool does not know. For a legal or a contract deadline, check the exact rule with the office that sets it.
