September 2026 calendar

There are 30 days in September 2026. The first is a Tuesday, the last a Wednesday. That's month 9 of 2026 and part of Q3. Counted from January 1 it spans days 244 to 273, with 92 still to come. It covers ISO weeks 36 to 40, which matters if your rota or term dates run on week numbers. Of the 30 days, 22 are weekdays and 8 fall at the weekend: 4 Saturdays and 4 Sundays, plus five each of Tuesdays and Wednesdays.

There is one public holiday in the United States this month, namely Labor Day on Monday September 7. Expect schools and most offices to be closed, and plan anything that needs other people around them. September usually means Labor Day, the start of the school year and the beginning of fall, and in most households that shows up in the diary as term timetables, new schedules and Q4 planning. All of it is already on the grid above, so you don't have to write any of it in yourself.

Everything above is editable. A click puts the cursor in a day, and what you type stays put. Most people use it for appointments and birthdays, but shifts, bill dates and school runs work just as well. If you're not signed in, those notes stay in this browser and go no further. Sign in and they follow you to any device. The small dot in the corner of each day sets a highlight colour, handy for marking who's on duty or which deadline actually matters. Happy with it? Print gives you the grid and your notes on a clean page, with the menus, buttons and adverts stripped out. Download PDF hands you the same thing as a file.

Sunday sits in the first column, as most US and Canadian calendars do it. You can change that under Options, along with ISO week numbers, whether holidays show at all, and how tall the rows are. Changing country at the top swaps the holiday set, so the September 2026 grid works just as well for UK bank holidays or German Feiertage as it does for US federal ones. There are downloads too: this month as a PDF at any of five paper sizes, or the full year as an Excel workbook, one sheet per month.
