Frequently asked questions
Does this count the start and end date both as full days?
The days-between calculation counts the number of full 24-hour periods between the two dates, which is the standard way most calendar tools report a date difference.
Can I subtract days going backward from a date?
Yes — the add/subtract mode lets you choose either direction from your starting date.
