The Tzolk’in or Sacred Calendar ¨ 260 days ¨ Made up of two calendars that fit together like the gears of a clock ¨ The first gear was a count from 1 to 13 ¨ The second gear was a series of 20 glyphs representing the god to be worshiped. The Haab or vague year 365 days ¨ 18 months each with 20 days ¨ One 5 day month known as Wayeb was considered unlucky and dangerous ¨
