Assumptions
- By default, the count is exclusive of the end date (e.g. Jan 1 to Jan 2 is 1 day) — a common point of confusion for day-count tools, so an explicit checkbox controls it.
Frequently asked questions
Should I include the end date in the count?
It depends on your use case — counting nights of a hotel stay is usually exclusive, while counting total calendar days covered (like a rental period) is often inclusive. Toggle the checkbox to match your need.
How is this different from the Date Difference Calculator?
This gives a single total-days figure (plus a weeks breakdown); the Date Difference Calculator gives a full years/months/days breakdown instead.
Does this exclude weekends or holidays?
No — this counts every calendar day. See the Business Days Calculator if you need to exclude weekends.
