October 31, 2026 falls on a Saturday

What day of the week is October 31?
In 2026 it is a Saturday. 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 October 31 works its way around the week rather than repeating on a tidy schedule.
