Weekday calculator
A weekday calculator names the day of the week for a calendar date. Once the date is fixed, the weekday does not depend on timezone. This page does not replace the holiday articles — it only notes observed US federal holidays when the date matches.
What day of the week is this date
ISO week numbers live on the week number tool.
Weekday calculator FAQ
Which calendar is this?
The Gregorian calendar, UTC date. The weekday of a calendar date does not depend on timezone once the date is fixed.
What about holidays?
If the date is an observed US federal holiday, the breakdown names it. Use the holiday pages for the full article. State holidays are not listed.
Is the week Sunday-first?
Weekday names run Sunday through Saturday, matching the US calendars on this site. ISO weekday numbers Monday = 1 through Sunday = 7 are also shown because ISO weeks start Monday.
Can I list the next Fridays?
Yes. Switch to Next occurrences, pick a weekday, and list up to 52 dates. Extra dates, save, and print need scripting; today’s weekday stays in the HTML.
