About December 2025
December 2025 has 31 days. The month begins on a Monday and ends on a Wednesday. It is the 12th month of the year and falls in the spring or winter portion of the academic calendar.
For US schools that follow the August-to-July academic cycle, December 2025 sits inside the 2025–2026 school year. Most K-12 districts end the fall semester during this month and enter winter break around the third week, returning in early January.
How to print
This calendar is designed to print cleanly on US Letter (8.5 × 11 in) and ISO A4 (210 × 297 mm) paper without scaling. Use your browser's Print menu (or the Print button above), select the orientation that matches the layout you chose — Landscape in this case — and disable headers and footers for the cleanest result. The grid is tuned for monochrome and color printers; holiday shading uses a soft amber that prints well in grayscale.
