Calendar Correlation
Sven Gronemeyer
This is a Java-Script based conversion programme. You can only enter Long Count information that can be converted into Calendar Round date, Gregorian Date and Julian Day Number. There is only a one-to-one relation in computing the result. Therefore, vacant digits or wildcards are not allowed.
Note: the converter only allows Long Count dates after the creation date to be entered. The calculation of mythological dates is not possible. Erroneous values will be corrected to the minimal or maximal possibility for each coefficient.
The preset correlation constant is the standard GMT with the value “584285”. But any other number between 250000 and 850000 can be entered. Lesser or higher values will be corrected to the minimal or maximal possibility.
We also include two correlation programmes for download that are rather old, from before the mid-nineties, and need to be run under DOS-Mode. We still consider them to be quite useful as none of the newer programmes that run under Windows offers the same variety of modes.
The software is provided in a zipped archive and needs no further installation.
Windows Vista and Windows 7 users: In order to get the software running, you need to install a DOS emulator first and run the software from there. The compability mode won’t function. DOS Box is a suitable tool. Users of Windows XP and below can run the software from the command line or via the compability mode.
