A significant feature of the community was its calendar, which was based on a solar system of 364 days, unlike the common Jewish lunar calendar, which consisted of 354 days. The calendar played a weighty role in the schism of the community from the rest of Judaism, as the festivals and fast days of the group were ordinary work days for the mainstream community and vice versa.

According to the calendar, the new year always began on a Wednesday, the day on which God created the heavenly bodies. The year consisted of fifty-two weeks, divided into four seasons of thirteen weeks each, and the festivals consistently fell on the same days of the week. It appears that these rosters were intended to provide the members of the "New Covenant" with a time-table for abstaining from important activities on the days before the dark phases of the moon's waning and eclipse (duqah).
