Count the days, weeks, months and business days between two dates, or add and subtract days, weeks, months and years from a date.
The calculator counts calendar days between two dates and also shows the gap in years, months and days, weeks, hours and business days (Monday to Friday).
Months are counted on the calendar: 31 January plus one month is 28 (or 29) February.
Subtract the earlier date from the later one. From 1 January to 31 December of a non-leap year is 364 days, or 365 if you include the end date.
No. Business days skip Saturdays and Sundays only, because public holidays differ by country and region.
Choose Add or subtract days, leave the start date blank and enter 90 days.
