The dates in September 2028
The Monday-first version uses 5 rows; the Sunday-first version uses 5. Changing the first weekday changes the layout, while every event remains attached to its actual date.

Keep recurring dates distinct from extra reminders
September ends on day 30. A monthly day-31 event is skipped; a September 30 reminder is a separate date. If you import an event list for the month, check duplicate IDs and the actual year before confirming so an older September project does not overwrite your current plan.
Optional U.S. federal holidays
These entries come from the reviewed 2026–2028 U.S. federal collection. Holiday dates and observed dates stay separate when they differ. The collection does not describe every school, state, local or business schedule.
| Date | Holiday | Date role |
|---|---|---|
| September 4, 2028 | Labor Day | Holiday and observed date |
Make the page useful on paper
Preview the whole sheet at the selected A4 or Letter size. Check the longest event label, the last date and any notes or legend. If the page is crowded, shorten supporting text or give the layout more space without changing the event dates.
Open this month in the editor before adding events. Choose the paper, orientation and week start on the same page, then download a fresh output after any change. Keep a JSON project backup if you want to revise the calendar later.
