Frequently Asked Questions
Does this include the start date?

Can I calculate days before a date instead of after?
Yes — just enter a negative number of days (e.g. -30) to calculate backwards from the start date.
Does this account for leap years?
Yes, all calculations automatically account for leap years and varying month lengths.
