Days between two dates

Pick a start and an end date to see how far apart they are.

How the count works

By default the count is the number of midnights you pass going from the start date to the end date, so Monday to Friday is 4 days. Tick Include the end date when both days should count, for example when working out how many days an event or a hotel stay spans, and Monday to Friday becomes 5.

The years, months, and days breakdown first adds as many whole months as fit, then counts the leftover days. When a start date falls on a day that a shorter month does not have, that month ends on its last day: from January 31 to March 1 is 1 month and 1 day, because one month after January 31 is the end of February.

Hours assume 24-hour days. A day that contains a daylight-saving change is really 23 or 25 hours long on the clock, but it is still one calendar day, which is what this tool counts.
