March 15, 2027 falls on a Monday
March 15, 2027 is a Monday. It is 172 days from today, September 24, 2026. The date is day 74 of 365 in 2027, it sits in ISO week 11, and it is the 15th of a 31-day month with 16 days after it.
What day of the week is March 15?
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 March 15 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 also moves: March 15 is day 74 in a common year and day 75 in a leap year, because it sits after 29 February.
How often does March 15 fall at a weekend?
