With two-bis being the misinterpretation of "every four years" in the
Julian calendar, so that Feb 29th was added every *three* years for some
time (Wikipedia suggests the most likely sequence was 44, 41, 38, 35, 32,
29, 26, 23, 20, 17, 14, 11, 8 BC, then a hiatus to correct the problem,
then AD 4, 8, 12 etc.).
