What day of the week is any date?

The weekday of a date is not fixed: it belongs to the date in a particular year. A common year of 365 days is 52 weeks plus one day, so a fixed date steps forward one weekday from one year to the next. A leap year adds a second spare day, so the step becomes two whenever 29 February falls inside the gap. Over 28 years the pattern closes and a date has visited every weekday four times, which is the cycle each date page counts out rather than assumes.

What day of the week is it today?
A Wednesday. Today is Wednesday, September 23, 2026.
Why does the same date fall on a different day each year?
Because 365 days is 52 weeks plus one spare day, so a fixed date moves forward one weekday a year, or two across a leap day.
Does 29 February have a page?
Yes. It exists only in leap years, so its date page lists leap years only.
