Mishmarot
Question
Please forgive my ignorance on the subject. I am interested in learning about the courses of the Levitcal priesthood. Each family performed their duty in the tabernacle, as I understand it, after the 24 courses. Each family performed their duties one week per course. All the priests would perform thier duties on holy feast days (three times a year, correct?) That would leave each family with two weeks out of the year for a total of five weeks. My question is, how would the courses be divided up in the month Adar? (the thirteenth month). After that, would the courses start with the same family on the Jewish New Year? Or would the thirteenth month make a different course occur?
