The Traditional Christian Calendar year is divided into four quarters of equal length, named for the gospels, and each contains three months, named for the first apostles. Phases of the sun and moon are not explicitly considered by the calendar, but it is hardly less lunisolar than the Julian calendar. Two different kinds of weeks are employed: the longer one, like ours, has seven days and originates in the story of genesis, the shorter one has just five days and there are 72 thereof in a year, commemorating Jesus’s disciples.
