The calendarwheel shows the way in which the Maya
connected the daynumbers to the glyphs of that day.
The wheel comes back to the same combination
of number and glyph after 260 days (13x20).
This is the maya ritual(moon) calendar called Tzolkin.
To the right are the monthglyphs.
Every month consists of 20 days,
except the last (19th) one of 5 days.
Together they make 365 days.
This is the sun calendar called Haab.
