Days between dates calculator
Count the days and weeks between two calendar dates, with an option to include the end date.
How to use this tool
Choose a start date and an end date. The default result measures the difference between calendar dates; the same date gives zero days. Include the end date to count both dates, giving one day for a same-day range. Calculations use UTC calendar dates so daylight-saving changes do not add or subtract a day. This does not calculate business days or public holidays.
