Frequently asked questions
How accurate is the date arithmetic?
Exact to the day. The calculator handles month-length variation, leap years (Gregorian rules), and end-of-month clamping correctly. Results match standard calendar libraries (JavaScript Date, ISO 8601, Java Time API).
Does the calculator handle dates across centuries?
Yes. Date arithmetic works for any date from 0001 to 9999. Leap-year exceptions for century years (1900 was not a leap year because not divisible by 400; 2000 was) are handled automatically.
Can I use this for legal or financial deadlines?
For calendar-day deadlines, yes. For business-day deadlines (excluding weekends and holidays), use the dedicated Business Days Calculator. Always verify against your specific contract or regulation — some jurisdictions have unique counting rules.
