Quick gap calculations — how many days since an event, how many days until a deadline, or verifying a date range in a report.

Is the count inclusive of the end date?

You can toggle inclusive/exclusive. Default is exclusive (counts the gap, not both endpoints).

Days Between Dates gives a single total day count. Date Difference breaks it into years, months, weeks, and days.

Is anything sent to a server?
