December 2025 Printable Calendar – Monday Start

A Month That Begins on a Monday

December 2025 starts on Monday the 1st, which is the alignment a Monday-start grid is designed for: every row of the month holds exactly one Monday-to-Sunday week, with no leading or trailing fragment to work around. Four complete weeks run from the 1st through the 28th — the 1st to the 7th, the 8th to the 14th, the 15th to the 21st, and the 22nd to the 28th — and a short final row covers Monday the 29th through Wednesday the 31st. Thirty-one days, eight weekend days — four Saturdays (6, 13, 20, 27) and four Sundays (7, 14, 21, 28) — and 23 weekdays.

Christmas Falls on Thursday, December 25

Christmas Day is Thursday the 25th, in the fourth row of the grid. Banks, post offices, and federal buildings are shut on the day, and the mail does not go out. Its weekday placement shapes the holiday period more than the date itself: a Thursday holiday splits that week into two short halves, and the Friday that follows, the 26th, is commonly given as an additional day off by private employers even though it is not a federal holiday. In practice, the last full working week of the year is the one ending Friday the 19th; everything after that runs at reduced capacity.

Working Backwards From the Holidays

The useful property of a Monday-start December is that deadlines can be counted in rows rather than days. With Christmas in the fourth row, the shipping and approval deadlines that matter fall in the second and third:

• Row 1 (1-7): set the month's commitments and place any gift or card deadlines where they belong.
• Row 2 (8-14): the practical cutoff for standard parcel shipping and for requests that need a response before the holidays.
• Row 3 (15-21): the last full working week. Treat Friday the 19th as the effective end of the business year.
• Row 4 (22-28): Christmas on the 25th; almost no coordination happens here.
• Row 5 (29-31): three days, ending the year on a Wednesday.

Closing the Year and Opening the Next

The final three days of December are easy to waste, and they are also the quietest working days of the year. Two tasks fit them well: closing out the current year's records, and writing down the first week of January while the calendar is still blank. Because January 1, 2026 falls on a Thursday, the next year also opens with a broken first week — the first working day is Friday the 2nd — so any plan that assumes a running start on Monday the 5th should be written now rather than improvised later.

Why the Layout Suits a Holiday Month

With Christmas in the middle of a row and no federal holidays elsewhere, the main risk in December is losing track of which week is still a normal working week. On this December 2025 printable calendar with Monday start, each row is one week, so the answer is visible: rows one through three are ordinary, row four contains the holiday, and row five is a three-day tail. Weekend columns sit together at the right, making it obvious which Saturdays and Sundays are still free for shopping, travel, or rest.

Printing the Sheet

One page of A4 or US Letter paper covers all 31 days, in color or black and white. Boxing the weekend columns is worth doing here, since the holiday season makes weekend commitments crowd in faster than usual.
