📅 Days Between Dates Calculator
Pick two dates, get the gap four ways: total days, weekdays only, complete weeks, and the calendar years-months-days breakdown.
30 days
End date excluded (elapsed days). Weekday count doesn't subtract public holidays.
How the days between dates calculator works
Total days are computed from UTC day numbers, immune to daylight-saving shifts that make naive millisecond subtraction land on 23- or 25-hour "days". The weekday count covers the span excluding the end date, the convention for counting working days until a deadline. The calendar breakdown counts complete years, then months, then days, handling unequal month lengths correctly.
Off-by-one is the classic trap: 1 July to 3 July is two days elapsed but three days touched. This tool reports elapsed days (end date excluded); add one if your use case counts both endpoints, as some contract-day conventions do. The weekday count also ignores public holidays, subtract those for your country manually.
Frequently asked questions
Is the end date included in the count?
No, the tool counts elapsed days, so Monday to Friday of one week is 4 days (and 4 weekdays). If your context counts both endpoints inclusively, add one.
How are weekdays counted?
Every Monday, Friday in the span, excluding the end date. Public holidays are not subtracted. They vary by country and year, so check your local calendar for those.
Does daylight saving time affect the count?
Not here: dates are compared as calendar days via UTC day numbers, so 23- and 25-hour DST days still count as exactly one day.
Can I count days between dates years apart?
Yes, any range the browser date picker accepts, with leap years handled by the calendar arithmetic. Century-spanning ranges are fine.
Are my dates uploaded?
No, the arithmetic runs on your device. Nothing is transmitted or logged.
