The first, known as the Calendar Round, was based on two overlapping annual cycles: a 260-day sacred year and a 365-day secular year. Under this system, each day was assigned four pieces of identifying information: a day number and day name in the sacred calendar and a day number and month name in the secular calendar. Every 52 years counted as a single interval, or Calendar Round. After each interval the calendar would reset itself like a clock.

They also used astrological cycles to aid in planting and harvesting and developed two calendars that are as precise as those we use today.
