Implementation of the Mayan calendar system. The Mayan calendar consists of several interlocking cycles including the Long Count, Haab (365-day civil calendar), and Tzolkin (260-day ritual calendar).

Key features:

• Long Count: B'ak'tun.K'atun.Tun.Winal.K'in format
• Haab: 18 months of 20 days + 5 Wayeb days
• Tzolkin: 13 numbers × 20 day names = 260 days
• Calendar Round: 52-year cycle combining Haab and Tzolkin
