September 2026 calendar
September 2026 fills five week rows, opening on a Tuesday and closing on a Wednesday. This page prints the month at the honest size of your paper — Letter or A4 — with Labor Day marked in its cell on Monday the 7th. It is the sheet that goes up when the school year starts and the summer improvisation ends.
Holidays in September 2026
Every date in the list below is computed against September 2026's real weekdays from the federal holiday rules — nothing is carried over from a previous year's table. Entries flagged federal are also marked inside their grid cell; observances appear in this list only, leaving the printed cells uncluttered. September keeps the rules simple this year: one federal date, landing on a Monday, so no observed-day substitution applies.

How this September 2026 page works
September is the month the household calendar stops being decorative. Term dates, practice schedules, and the first round of forms all arrive inside the same fortnight, and they arrive on paper more often than anywhere else. Thirty days is a forgiving grid to plan on — five clean week rows, no stray sixth — and the month opens on a Tuesday, which puts the first weekend a comfortable distance from the first Monday back. The coloring-top layout compresses the grid into the lower part of the page and opens a blank framed panel above it, so a child can fill the space while the adults fill the cells.
The sheet in the preview is the sheet that leaves the printer. It is drawn as SVG whose units are real millimeters, and when the print dialog opens, the page declares the exact dimensions of Letter or A4 stock — the browser then acts as its own PDF generator, laying the grid onto a surface whose size it knows precisely. Nothing here is transcribed. The code asks which weekday opens the month — a Tuesday — counts out 30 days, and places each in turn, wrapping five week rows deep. Labor Day appears in its cell because the first-Monday rule resolved to the 7th, not because a table said so.
Know what the sheet leaves out. There are no week numbers along the edge and no lunar phases in the corners — additions that suit some planners and clutter others. Non-federal observances are listed below the sheet for reference but never marked inside the cells; the grid reserves its ink for the federal set. If your week runs Monday to Sunday, the Monday-start option rebuilds the grid accordingly — still five rows for this month either way, so switching layouts does not change how tall the grid stands. And one setting decides whether the millimeter rules print or stay off the page.
