The Calendar Round
The calendar round is the third type of calendar used by the Maya. It is basically nothing more than the combination of the two calendars Haab and Tzolkin.
For this purpose, the two calendars were turned against each other like two interlocked gears and the respective calendar entries were combined.
First, the date from the Tzolkin calendar is noted. Second, the corresponding date of the Haab calendar is added.
A simple date of the calendar round would look like this:
2 Ik 0 Pop
The next day would be
3 Akbal 1 Pop
And the next following day would be
4 Kan 2 Pop
The easiest way to understand the Calendar Round is to imagine the days of Tzolkin and Haab located on two different sized, meshing gears. Every day, both wheels turn further by one tooth.
Since the two cycles of the Haab and Tzolkin have different lengths, the combination of the two calendar systems gives unique day names.
These day names repeat only after 52 Haab years or after 18,980 days.
This method is quite useful for recording short periods of time. But if you want to document longer periods over several generations, then the system reaches its limits soon. Therefore, the Maya used an additional system: The Long Count
