September 1, 2027 falls on a Wednesday
September 1, 2027 is a Wednesday. It is 342 days from today, September 24, 2026. The date is day 244 of 365 in 2027, it sits in ISO week 35, and it is the 1st of a 30-day month with 29 days after it.
What day of the week is September 1?
In 2027 it is a Wednesday. 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 September 1 works its way around the week rather than repeating on a tidy schedule.

Between 2026 and 2027 the weekday moves from Tuesday to Wednesday, a step of 1. The day-of-year column also moves: September 1 is day 244 in a common year and day 245 in a leap year, because it sits after 29 February.
How often does September 1 fall at a weekend?
Counting the 28 occurrences from 2027 to 2054, September 1 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.
