The twelve months of Maskaram, Tepemt, Khedar, Takhsas, Ter, Yakatit, Magabit, Miyazya, Genbot, Sane, Harnle and Nahase each have thirty days and the remaining days are in Paguemen.
The intercalary month has 5 days on non-leap years, 6 days on leap years. Every fourth year is a leap year, with no exceptions. Thus, a(n) = a(n-52). - Jon E. Schoenfield, Feb 16 2015

As Antti Karttunen points out, this cannot be right as there are 15 or 16 30's between pairs of 5's, not 11. - N. J. A. Sloane, Aug 25 2002
