September 23, 2026 falls on a Wednesday
September 23, 2026 is a Wednesday. That is today. The date is day 266 of 365 in 2026, it sits in ISO week 39, and it is the 23rd of a 30-day month with 7 days after it.
What day of the week is September 23?
In 2026 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 23 works its way around the week rather than repeating on a tidy schedule.

Between 2026 and 2027 the weekday moves from Wednesday to Thursday, a step of 1. The day-of-year column also moves: September 23 is day 266 in a common year and day 267 in a leap year, because it sits after 29 February.
How often does September 23 fall at a weekend?
Counting the 28 occurrences from 2026 to 2053, September 23 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.
