The Sun's Circle is a 28-year calendar cycle, associated with the repetition of combinations of days of the week and dates in the Julian calendar. In the Easter tables, it helps to determine Sunday and weekly correspondences. In the tables, the Sun's Circle can be written as a fraction, for example 267/1. The first number means the number of the 28-year solar cycle from the creation of the world, the second number the year within this circle. For 1941, which corresponds to the summer of 7449 from the creation of the world, the table shows 267/1: this is the 267th solar cycle and the 1st year within it.
