I've seen "lunar calendars" that show the year divided by Gregorian months (slicing the lunar cycles oddly), but not the other way around. So I made one! https://observablehq.com/d/af965f24c17b16e5
In doing so, I realized Nov 2024 is pretty special; it aligns perfectly to the lunar cycle 🌑🌓🌕🌗 Neat!
