Days between dates
Pick two dates to get the exact number of days between them — plus the same span in weeks.
Pick two dates to compare.
How it works
The calculator counts whole calendar days from the first date to the second. A negative span means the second date is earlier than the first. Dates are handled in UTC internally, so a daylight-saving change never adds or drops a day. Everything runs in your browser — nothing is sent anywhere.
Common uses
Count down to a holiday or festival, work out a notice period or deadline, check how many days until a trip, or measure the gap between two events. For the date of a specific festival, see the holiday calendars by country.
