add days to a date
30, 60 or 90 day terms appear in contracts, warranties, trial periods and billing. The calculator below adds or subtracts days, weeks, months and years to a date and also shows the arrival weekday, so you do not schedule anything on a Sunday by accident.
It crosses the end of October (31 days), so it does not land on 11-06.
It crosses the new year.
A common year: the date returns to the same day and month, one weekday ahead.
End-of-month rule: February 2026 has no 31st, 30th or 29th.
Subtract one date's day number from the other's. The tool does this in whole days, unaffected by time zones or daylight saving. From 2026-01-01 to 2026-12-31 is 364 days, or 365 if you also count the last day (the "Also count the last day" option).
No. The standard calculation adds 90 to the starting day, so today is day 0. If your term counts today as the first day, the end date is one day before the result shown.
Yes. In Add/subtract mode, add steps (up to 8). Each step starts from the previous result, and the timeline shows each step, including where an end-of-month adjustment happened.
From 0001-01-01 to 9999-12-31, in the extended Gregorian calendar. If the result falls outside that range, the tool says so instead of showing a wrong value.

The tool advances whole months from the start date without passing the end date, then counts the leftover days. When the start day does not exist in the target month (the 31st in February, for example), it uses that month's last day.
Example: from 2026-01-31 to 2026-02-28 is exactly 1 month; from 2026-01-31 to 2026-03-01 is 1 month and 1 day (Feb 28 plus 1 day). The total of days, weeks, hours, minutes and seconds is exact and does not depend on this convention.
Need to count only business days, without weekends and holidays? Use the business days calculator.
Proleptic Gregorian calendar, from 0001-01-01 to 9999-12-31, in pure dates: no time zone and no daylight saving. Before October 15, 1582 the Julian calendar was in use, so old dates here may differ from historical records.
