What this means
This compares two calendar dates directly and counts the day gap between them.
Formula used
Days between dates = end date - start date, with an optional +1 if you include both dates.
Worked example
From 1 April to 10 April is 9 days apart, or 10 days if you count both the start and end date.
Common questions
Why does include both dates change the result?
It counts the starting day itself as part of the total, which is useful for bookings, countdowns, and schedules.
Does this count working days?
No. This is calendar-day math, not workday logic.
Plain-English summary
That is the calendar gap between the two dates, which is useful for planning and countdowns.
This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.
