What if... we removed the month-ends? I typically imagine time as a line, so I wondered what it would look like if days were rects in one line, just word-wrapped. It doesn't auto-adjust to page size, but 75% zoom works fine for printing in my case. https://igormartynov.com/calendar2026.html
A variation of that one with month names: https://bigasterisk.com/post/2026%20Calendar%20-%20Print%20-...
Note that you can align the weeks (or not) by adjusting the width at print time.
