September 5, 2027 falls on a Sunday
September 5, 2027 is a Sunday. It is 346 days from today, September 24, 2026. The date is day 248 of 365 in 2027, it sits in ISO week 35, and it is the 5th of a 30-day month with 25 days after it.
What day of the week is September 5?
In 2027 it is a Sunday. 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 5 works its way around the week rather than repeating on a tidy schedule.
