On the Gears tab, you can see an animated view of how the Calendar Round works, showing the interlocking between the Tzolk'in and the Haab.

This allows working with Aztec dates, post-classic Maya dates, and dates spelled using your favorite orthography . The program provides some of the most commonly used profiles, but you can add others. The Light version of the program only supports the most standard profile.
The Maya Calendar is complicated. The program comes with an extensive description on how the Maya Calendar works.
The Light version allows you to put in a Gregorian, Julian, or Maya date and find the corresponding dates in other systems. The Professional version adds an incredibly powerful search feature, using a proprietary search algorithm based on number theory. It allows partial information about Maya dates to be entered and it will find all of the possibilities that match the criteria.
The Copy button on the ribbon places information on the Windows clipboard. This information can be pasted into a word processing program such as Microsoft Word. The Professional version adds another very useful feature: If you have Microsoft Excel, the Excel button will invoke Excel and install a library of Maya Calendar functions that can be used in any Excel worksheet. This allows analysis of sets of dates.
Maya dates work in both the current and previous Maya epoch. Dates can be seen up to 10 trillion years in the past. You can see the calculated supplementary series glyphs, and the Gregorian, Julian, and Julian Day number for any Long Count date.
The Light version supports common years such as 3114 BCE for years before 1 CE. The Professional version adds support for astronomical years such as -3113 for years before 1 BCE. Astronomical years assume that there is a year zero.
The main window expands to the size of the screen. This is ideal for using a projector to teach about the Maya Calendar in a classroom.
The program has been designed to support different languages. It currently supports English. Other languages will be supported as we find translators. We will be supporting Spanish soon, and are particularly interested in translating into the Mayan languages such as Yucatec, Ch'ol, Kaqchikel, and K'iche' so that these different Maya subgroups can learn more about their calendar. If you are biligual and wish to volunteer to translate the interface into a particular language, let us know on the contacts page.
