What day of the week is January 4?

In 2027 it is a Monday. The weekday is not a property of the date itself, it is a property of the date in a given year, so the honest answer always names the year. A common year is 365 days, which is 52 weeks plus one spare day, so a fixed date moves forward one weekday from one year to the next. A leap year inserts a second spare day, so the step is two whenever 29 February falls inside the gap. That is why January 4 works its way around the week rather than repeating on a tidy schedule.

Between 2026 and 2027 the weekday moves from Sunday to Monday, a step of 1. The day-of-year column never moves for this date, because January 4 comes before 29 February and so is untouched by the leap day.

How often does January 4 fall at a weekend?

Counting the 28 occurrences from 2027 to 2054, January 4 lands on a Saturday 4 times and on a Sunday 4 times, so 8 of those 28 years put it at a weekend. Over a full 28-year stretch the Gregorian calendar repeats itself, and a fixed date visits each weekday four times, so the long-run answer is two weekend years in every seven.
