Next: Working days calculatorThe same span, with weekends taken out.
The difference does not count the start date. Weekdays are Monday to Friday, with no holiday calendar.
How this is calculated
- Step 1
Two dates
Order does not matter. The earlier one is the start.
- Step 2
The gap
End minus start leaves the start date out.
- Step 3
Both ends
The inclusive count adds the start back in, and weekdays are counted.
Calendar difference
difference = later − earlier, in calendar days
| difference | End minus start. Same date is 0. |
|---|---|
| inclusive | Difference plus one, counting both dates. Same date is 1. |
| weekdays | Mondays through Fridays inside the inclusive span. |
A stay that begins on 1 May and ends on 4 May is a difference of 3 days and an inclusive count of 4 dates.
Order does not matter. If the first date is later, the tool still reports the span and says which date came first.
Weekdays ignore public holidays. The working-days calculator subtracts a holiday count you type. To land on a date a known number of days away, use days from today.

Are both dates included?
The headline number does not include the start date. It is the calendar difference. “Counting both dates” adds one. On a single date those two numbers are 0 and 1.
Which days count as weekdays?
Monday to Friday, inside the inclusive span. Saturday and Sunday are left out. This page does not subtract holidays. The working-days calculator does, once you type how many weekday holidays fall in the span.
What if I enter the later date first?
The span is the same. The result says which date is earlier instead of printing a negative number.
Does the time of day matter?
No. A date is a civil day. Crossing a time zone does not add or remove a day here.
