Days Between Dates counts how many days (and related week/month views) sit between two calendar dates when a mental count is unreliable.
Turn on Include end date when contracts or hotel stays bill the leaving day; leave it off when you only want the open interval.
The tool does not adjust for time zones. Pair it with a time zone converter when flights cross the date line.
