Frequently Asked Questions
Does this include the start date?
No. The calculator counts forward from the day after the start date, which is the standard way most date calculators work.
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.
