Days Between Dates
Two dates in — exact days, weeks, and a weekday estimate out.
How this is calculated
The count walks the real calendar (leap days included) and reports the difference — the "nights between" convention that deadlines and interest calculations use. Example: 27 February to 1 March 2024 is 3 days, because 2024 has a 29 February. The weekday line subtracts Saturdays and Sundays; public holidays are yours to subtract, since they differ by country.
Frequently asked questions
How are the days counted?
As whole calendar days between the two dates, end minus start — Monday to the next Monday is 7. Leap days are included automatically because the count walks the real calendar. Swap the dates and the sign flips.
Does it include the end date?
The default answer is the difference (nights between, exclusive of the end day) — the convention loans, deadlines, and date math use. If your context counts both endpoints ("day 1 to day 10 inclusive"), add 1 — the result panel shows that inclusive figure too.
How do I count only working days?
The result shows an estimate of weekdays (total minus Saturdays and Sundays) alongside the calendar days. Public holidays vary by country and year, so subtract those separately for exact business-day counts.
Can I count backwards from a date?
Yes — put the later date first and the result is negative, or just read the absolute number. For "what date is 90 days from X", the add-days calculator answers directly.
