Zalkin Calendar in Mayan Calendar

Mayan astronomers gave the Mayan version of the 260-day calendar of Central America (Tzolkin), but in the new orthography, they prefer to use the name Tzolkin, which is based on the Ugandan language and extended to "days" (COE 1992).

The exact name of this calendar in the pre-Columbian Maya period is still unknown, and the corresponding calendar in Aztec Navarra is called Thonnard Povali calendar.

Trecena cycle consisting of 20 days and 65,438+03 days constitutes 260 independent days, which are used to decide the time of religious and ritual activities and for divination. Each date is marked with the number of days from 1 to 13, and then starts again from 1. In addition, each date is marked with 20 Japanese names in turn: Zagreb's calendar: Japanese names and their corresponding characters. Examples of Japanese names come from16th century.

After that, the number of days (trecena) starts from 1 again, and the day name sequence continues to be calculated upwards, so the next combination is 1Ix, 2Men, 3K'ib', 4Kab'an, 5Etz'nab', 6Kawak, followed by 7Ajaw.

After 20 date names are used up, the date names start counting again, and the number part continues to accumulate, so the next day of 7Ajaw is 8 imix'. Therefore, it takes 260 days for all combinations of days and day names that connect 13 and 20 days to complete a cycle. The exact origin of Zalkin calendar is still unknown, but there are several theories.

According to one theory, the Zalkin calendar is derived from the mathematical operation of 13 and 20, which is a very important number for the Mayans. 20 is the cardinal number in the Mayan numeral system, which comes from the total number of human fingers and toes (see Mayan numerals for details), while 13 symbolizes the series in the celestial world where the gods live, and the multiplication of the two numbers is equal to 260.

Another theory mentions that the interval of 260 days comes from human pregnancy, which is close to the average number of days from the first menstrual period to the time when you should come and not come to give birth, instead of the 40 weeks (280 days) from the last menstrual period to delivery in Nigel's law, so some people speculate that the Zalkin calendar was originally formulated by midwives to estimate the expected date of delivery of babies.
