I want to know the answer to the following question:
How many months were in a year in the original Mayan calendars?
All the background I'm provided with is that "Lunisolar calendars have a thirteenth month added to some years to make up for the difference between a full year (now known to be about 365.24 days) and a year of just twelve lunar months.". Is that enough to answer the question?
Answer: no
