About this date
Monday, September 22, 2025 falls in ISO week 39, the 265th day of 2025, with 100 days remaining in the year. The 365-day span behind contains 261 weekdays and 104 weekend days. Months are stepped by the calendar rather than by a fixed 30 days, so the span varies with which months it crosses.
11 US federal holidays fall inside this span: New Year's Day on Thursday, January 1, 2026, Birthday of Martin Luther King, Jr. on Monday, January 19, 2026, Washington's Birthday on Monday, February 16, 2026, Memorial Day on Monday, May 25, 2026, Juneteenth National Independence Day on Friday, June 19, 2026, Independence Day on Friday, July 3, 2026, Labor Day on Monday, September 7, 2026, Columbus Day on Monday, October 13, 2025, Veterans Day on Tuesday, November 11, 2025, Thanksgiving Day on Thursday, November 27, 2025, Christmas Day on Thursday, December 25, 2025. That is why the business-day answer above differs from a simple weekday count.
