Show HN: Maya Calendar (mcal.qt.ax)

In a similar vein to the French Republican Calendar app I built a while back (https://frcal.qt.ax/, https://news.ycombinator.com/item?id=30658487), I built this implementation of the Maya calendar.

For some more details regarding the implementation, see https://quantum5.ca/2026/07/04/art-of-time-keeping-part-5-ma....
