Chac 2.1.2 - Mayan calendar.. (Free)

Chac 2.1.2 - Mayan calendar.. (Free): "

Chac is a complete accurate Maya calendar for the Macintosh.

Version 2.1.2:

• For version 2.1.2 I made the following changes:
• I fixed minor bugs in the activating or deactivating of the interface elements in the Calendar Round and date panels.
• I added a Distance number calculation panel. This was difficult because the algorithms for Julian day number, Tzol'kin, Haab' , day of the week and Long Count wouldn't work for negative numbers. The calculations can be done as far as 20 + or - 20 bak'tuns but you can only set the current inscription to the date in the panel if it's 0 - 19.19.19.17.19.
• I edited the help book to reflect these changes and made other substantial edits and improvements.
• I fixed a bug which caused maya dates to store their preferred year bearer system improperly.
