December runs on countdowns — concerts, closings, and winter break — and a printed month is the one countdown everyone in the house can see. The first square falls on a Monday this year and the last on a Wednesday, 31 days apart, and Christmas Day (Thursday, December 25) sits among them. It prints free as a one-page PDF with no signup and no watermark. Need a different month or a weekly planner? Open the printable calendar generator.

What's on the December 2031 calendar

Days: 31
The 1st falls on: Monday
Week rows: 5 on either week start
Federal holidays: Christmas Day

Every date is calculated from the calendar arithmetic itself rather than looked up in a table, so the weekday columns, week rows, and holiday placements above are exact for December 2031 — and the printed sheet matches the preview to the square.

Tips for the December 2031 calendar

December 2031 starts on a Monday, so the first week row has 1 empty square before the 1st — use them for month goals or a supply list.
Print December early and put winter-break camp sign-up deadlines on it — they close weeks before the break.
Circle Christmas Day on the 25th before filling anything else in — closures ripple into the days around them.
Print at 100% scale, not “fit to page” — the grid is laid out to the real paper size.
Need somewhere to write goals? Turn on the notes column before downloading — it adds a ruled panel beside the December grid.

Customization options

Week start

Sunday or Monday. The whole December 2031 grid is rebuilt around the choice — every date moves to its correct new column, and the week-row count adjusts if the month re-flows.

US federal holidays

On by default: each holiday is printed by name in the square it falls on, and the square is tinted. Turn the option off for a clean grid. The date marked is always the holiday itself, not the weekday federal offices observe it on when it lands on a weekend.

Notes column

Adds a ruled panel down the right-hand side of the December 2031 grid for goals, reminders, or a running list. It is off by default because the plain full-width grid is what most people pin up.

Orientation and paper size

Portrait or landscape, on US Letter (8.5 × 11 inches) or A4 (210 × 297 mm). The page is genuinely rotated rather than scaled, and the grid is recalculated to fill whichever sheet you choose.

Frequently asked questions

What day of the week does December 2031 start on?

December 1, 2031 falls on a Monday, and the month ends 31 days later on December 31, a Wednesday. The calendar above places every date in the correct column — the arithmetic is calculated, not looked up.

How many days does December 2031 have?

December 2031 has 31 days, including 4 Saturdays and 4 Sundays. On the printed sheet those weekend columns are lightly tinted.

Which federal holidays fall in December 2031?

December 2031 contains Christmas Day (Thursday, December 25). With holidays turned on, each is printed by name in its square and the square is tinted. The date marked is the holiday itself — where one falls on a weekend, federal offices observe it on the adjacent weekday, which is a fact about offices, not the date.

How many week rows does the December 2031 calendar have?

December 2031 spans 5 week rows on either start. The grid is rebuilt around your week-start choice, and the squares grow to fill the page, so a 5-row month prints with taller squares than a 6-row one.

How many weekends does December 2031 have?

4 Saturdays and 4 Sundays. Both weekend columns are tinted on the printed sheet, so the working weeks read at a glance.

Is the December 2031 calendar free to print?

Yes — completely free. No signup, no email, no watermark, and no limit on copies. The PDF is generated in your browser and downloads instantly.

Can I print December 2031 in landscape or on A4?

Yes. The December grid is recalculated for portrait or landscape on US Letter or A4, genuinely rotated rather than scaled — nothing is squashed or clipped. Print at 100% scale.
