Frequently Asked Questions (FAQ)
Q. Does the day count include both the start and end dates?
A. This tool displays the difference between the start and end dates. For example, from January 1 to January 3, the result is 2 days. If you want to count inclusively (3 days), add 1 to the result.
Q. Are leap years taken into account?
A. Yes, leap years (February 29) are correctly handled. The tool uses JavaScript's Date functionality, ensuring accurate leap year calculations.
Q. Can I calculate with past dates?
A. Yes, past dates work perfectly. For the days-between calculation, swapping start and end dates still gives the correct result. For the date-offset calculation, enter a negative number to find a past date.
