 OFFSET 1,1 COMMENTS The index is 0-based, so 0 = Sunday, 1 = Monday, 2 = Tuesday, 3 = Wednesday, 4 = Thursday, 5 = Friday, 6 = Saturday. The first term in the sequence represents the day of the week index for January 1, A.D. 2000. The sequence repeats after 4800 terms, representing 400 years in the Gregorian calendar system. LINKS Lyle P. Blosser, Table of n, a(n) for n = 1..4800 EXAMPLE a(1) = 6, so day of week for January 1, 2000 is Saturday; a(2) = 2, so day of week for February 1, 2000 is Tuesday; a(3) = 3, so day of week for March 1, 2000 is Wednesday. CROSSREFS Cf. A178055. If a(n) is the n-th term of A178054 and b(n) is the n-th term of A178055, then a(n) + b(n) (modulus 7) = a(n+1).
