Finish the year without guessing the next holiday set
December 2028 ends on Sunday and needs six rows when Sunday is first. Check all thirty-one dates before printing. If your project continues into January 2029, keep that date range but show the reviewed holiday collection’s limit; do not fill the new year with unreviewed assumptions.
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 |
|---|---|---|
| December 25, 2028 | Christmas Day | Holiday and observed date |
Make the page useful on paper
At least one week-start choice needs six rows this month. Keep the final row and all its dates inside the paper margins. Check a busy cell and any event that continues across a row before choosing the final density.
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.
