December 2025 Printable Calendar

December 2025 Opens on a Monday and Ends on a Wednesday

The final month of 2025 covers 31 days, from Monday the 1st through Wednesday the 31st. Twenty-three of those days are weekdays and eight are weekend days — four Saturdays (6, 13, 20, 27) and four Sundays (7, 14, 21, 28). One federal holiday falls inside the month: Christmas Day on Thursday the 25th. Removing it leaves 22 federal working days, the highest total of the fourth quarter.

What the Month Looks Like as Rows

Because it begins on a Monday and runs 31 days, the grid produces four complete Monday-to-Friday weeks and a three-day tail. The complete weeks begin on the 1st, the 8th, the 15th, and the 22nd. The tail is Monday the 29th through Wednesday the 31st. The holiday sits in the fourth of those weeks, splitting it into three working days, a closure, and one more.

Christmas Day on Thursday the 25th

A mid-week Christmas has consequences on both sides of it. The week of the 15th is the last one that behaves normally, which makes it the place for anything requiring another person's attention. Standard parcel services generally cut off shipping in the week of the 8th, and the week of the 22nd keeps only three working days before the holiday. Friday the 26th is a working day on paper that most workplaces treat as part of the break. Federal offices, banks, and post offices close on the 25th and mail does not run.

The Year-End Close and New Year's Eve

December carries the obligations attached to the end of a calendar year. Financial close, payroll cut-offs, insurance renewals, and any accounting that runs on the calendar year all land in the fortnight before Christmas. Hanukkah begins on the evening of Sunday the 14th, which puts it mid-month rather than against the holiday. New Year's Eve falls on Wednesday the 31st, the last day of the year and the last working day for most organizations. The January that follows opens on a Thursday, which means the next year's first working day is a Friday standing by itself — a detail worth writing onto the sheet before the 31st arrives.

A Plan for a Month With a Short Tail

The three-day tail at the bottom of the grid is the detail most plans miss. Three working days is enough for wrap-up and not enough for anything substantial. The sequence that holds: place fixed year-end deadlines in the weeks of the 1st and the 8th, use the week of the 15th for review and handover, treat the week of the 22nd as three days plus a holiday, and reserve the 29th through the 31st for closing the year out rather than opening anything new.

Rolling Next Year Forward

December is also where the following year gets planned. The window that works is the week of the 15th, when the current year's work is winding down but attention has not yet moved to the holiday. Decisions made then have two clear weeks to settle before January begins, longer than most people allow themselves.

Printing the Sheet

Every day of the month lands on a single sheet, at full contrast whether you print in color or not. Marking the 25th first, then the four complete weeks, shows how much of the month is genuinely available. Use the print button for an immediate copy, or download the PDF if you would rather print later or keep the sheet with the year's records.
