Days between dates

The days between two dates, in days, weeks, months and years, with or without the last day. Free, with no account or uploads.

Count the days between two dates

Choose both dates. Turn on Count the last day too for a holiday or a leave.

Dates follow the Gregorian calendar back to year 1, as computers do; before 1582 (1752 in Britain and its colonies) records were kept in the Julian calendar, so old dates may differ from what was written at the time.

Questions people ask

Does it count the first and last day?
It counts the first day and not the last, as the nights between are counted. Turn on Count the last day too to count both.
Why is 31 January to 28 February not a month?
Months are counted from the first date's day of the month, so a month after 31 January would be 31 February, which does not exist; it is 28 days.
Can it leave out weekends?
Yes: ask for working days instead, and choose the country whose public holidays to skip as well.
