Conversion between Mayan Calendar and Western Calendar
At least one date in one calendar must be accurately mapped to the same day in another calendar in order to convert dates between two different calendars. The accepted conversion expression between Gregorian calendar or julian calendar and Maya calendar is the number of days from julian calendar to Maya's founding date./kloc-0 13.0.0.0.04ajaw8kumk 'u
The most widely accepted conversion is "Goodman, Martinez-Hernandez, Thompson" conversion (commonly known as "GMT"), and there is a so-called "original GMT conversion", which is actually the same conversion method as a Lounsbury conversion, which will cause confusion to most people. GMT conversion is to set the date of Maya's creation as julian calendar BC 313.0.0+065438+September 6, 2004 or Gregorian calendar 3 165438+August165438 or julian calendar 584283. However, many other conversion methods have been proposed in different periods. The following conversion method is almost purely based on historical considerations. In addition to the conversion method proposed by Floyd Lounsbury, it is only two days longer than GMT conversion and is still used by a few Mayan scientists.
Today, 65438+Thursday, October 23rd, 2008/kloc-0, is expressed in the long calendar as:12.19.15.14.0.
Many books about Maya and most software that can exchange Mayan calendars use Gregorian calendar. In this system, julian calendar date is modified to Gregorian calendar date, instead of using julian calendar before Gregorian calendar appeared. This is why the long calendar in 2004 was changed from 0.0.0.0 to 3165438+August 1 1.
Using software based on the old Gregorian calendar may cause the following problems:
1. Historical research: For example, the G.M.T transformation is based on the activity dates of Bishop Diego de Landa in Jugaton and Bishop Bernardino de sahagun in Mexico. If someone tries to use the previous Gregorian calendar-based program to get the correct conversion, it will not be feasible, because Germany.
2. Astronomical research: For example, when studying materials on ancient stone tablets or prints, some people will convert long calendars into years, months and days. Then input these dates into the astronomy program, but the program uses the standard julian calendar/Gregorian calendar, which will cause a major error.
Since most researchers will buy computer software to convert the Mayan calendar, it is obviously not irrelevant. It is necessary to know what system they are using.
The picture shows in detail the three lines of characters in the Ramojala stone tablet 1 in the 2nd century BC. The leftmost column indicates 8.5. 16.9.9 or 156 in the long calendar date. The characters in the two columns on the right are post-Olmec characters.
[Edit] Calculate the date of a long calendar
The date series of a long-term cumulative calendar starts with the highest time unit (Burktown), and then lists the smaller time units until the number of days (gold), and then the date of the calendar cycle.
A typical date in a calendar cycle is 9.12.2.0.165klbs'14klbs'. We can verify whether this date is correct by the following operations.
Maybe it will be much easier to find out the number of days that have passed since 13.0.0.04 Ajaw 8 Kumk 'u and show how the date was deduced in 5 Kib' 14 Yaxk'in.
