Why dates change weekday

A common year is 52 weeks and 1 day long, so a date usually moves one weekday later each year, and two after a February 29. The whole pattern repeats every 400 years, which is why every date's weekday can be worked out exactly.

Frequently asked questions

How do I find the day of the week for a date?

Choose the date in the form and press Find the day. If it's the next time that date comes round, you'll get its evergreen page; any other year opens a page for that exact date.

Which calendar is used for old dates?

The Gregorian calendar, extended backwards. Countries switched from the Julian calendar at different times (Britain and its colonies in 1752), so weekdays in older records can differ.

Do weekdays ever repeat on the same dates?

Yes. A year's calendar repeats after 6, 11 or 28 years, depending on where it sits in the leap-year cycle.
