The sun, moving in the outermost circle, travels for 18 muhurtas, minus 2/61 muhurtas, in a day, and 12 muhurtas, minus 2/61 muhurtas, in a night.
The sun, moving in the innermost circle, travels for 18 muhurtas, minus 4/61 muhurtas, in a day, and 12 muhurtas, minus 4/61 muhurtas, in a night.
Thus, as the sun moves from one circle to the next, it travels for 2/61 muhurtas in each circle, decreasing the day and increasing the night.
When the sun has traveled through all the inner circles and reaches the outermost circle, it travels for 3/61 muhurtas, minus 3/61 muhurtas, in a day, and 18 muhurtas, minus 12 muhurtas, in a night. This is the end of the first six months.
