How the count works
The standard result treats the starting date as day 0. Day 1 is the next calendar date. Select “Count the starting day as day 1” if your own task uses an inclusive count. This calculator counts every calendar day, including weekends and holidays.
Dates are calculated as calendar dates, so a daylight saving time change does not add or remove a day. The default “today” comes from UTC; use “Use my today” or choose a starting date when your local date differs. The calculator accepts 1–3,650 days and dates in years 1000–9999.

Using this date for a deadline?
Check the rule that applies to your deadline before relying on a calendar count. Some rules count business days, exclude the starting day, or move dates that land on holidays. This page does not determine a legal, immigration, or filing deadline.
