Date difference
Count elapsed days between two calendar dates.
Choose two valid calendar dates to measure the elapsed days between them. The tool interprets each date at midnight UTC and divides the difference by 86,400,000 milliseconds. Equal dates give zero, and an end date before the start produces a negative result.
How to use
- Enter your text, values, or image.
- Adjust the options and run the tool.
- Copy or download your result.
Limitations and details
The start day is excluded, and the result is a calendar-day difference rather than a business-day count or a calculation of local daylight-saving hours.
