Printable Calendar

Same button: in the print dialog, change the destination to 'Save as PDF' — built into every modern OS and browser. You get a vector PDF (razor-sharp at any zoom) sized to your paper. This is also how to send a calendar to someone else or archive a filled-planning month.

Sunday-first is the convention in the US and Canada; Monday-first matches ISO 8601 and most of the world's wall calendars. Pick the one your eye is trained on — misreading an unfamiliar layout is genuinely how appointments land on the wrong day. School and business planning in Monday-start countries should match, since 'the week of the 14th' means different boxes.

By choice: decoration costs ink, muddies photocopies, and shrinks the writing space, and a calendar's job is to be written on. Plain black rules on white print perfectly on any printer including laser, copy cleanly for a classroom set, and the empty boxes are the feature. If you want themed decoration, print this and let the kids supply it.

Yes — the grid is computed from the calendar rules directly (including leap years and century exceptions), so 1900 through 2199 render correctly. Handy beyond planning: checking what day of the week a historical date fell on, printing next year's months before wall calendars ship, and genealogy work.
