How to use
Pick a start and end date, choose which weekdays are your weekend, and optionally select a country whose public holidays should be excluded. The result breaks the range into calendar days, business days, weekend days and excluded holidays, and lists every excluded holiday date so you can verify the calculation.
Frequently asked questions
Which days count as business days?
By default Monday through Friday. You can change which weekdays count as the weekend — useful for regions where the weekend is Friday–Saturday — and optionally exclude a country’s public holidays.
What about holidays that fall on a weekend?
A holiday on a Saturday or Sunday is not double-counted: the day is excluded once as a weekend day. Countries that declare substitute weekdays (like the US or UK) have those substitute days in the holiday calendar, so they are excluded too.
Which countries have holiday data?
Holiday calendars are currently available for United States, United Kingdom, Canada, Australia, Germany, France, Japan, South Korea. They are generated from each country's published statutory rules; regional holidays are not included.
