A.4 Lunar Eclipses (150 every century; occur at night)

Full moons occur on the Julian days 2449129.09 + 29.53058885 n ± 0.5, where n is a half-integer.

Lunar eclipses are a special case of full moons, and occur when n mod 223 appears as shown in the next table.

0.5, 6.5, 12.5, *, 23.5, *, 35.5, 41.5,

47.5, 53.5, *, *, *, 76.5, 82.5, *,

88.5, 94.5, 100.5, *, *, *, 123.5, 129.5,

135.5, 141.5, *, 153.5, 158.5, 164.5, 170.5, 176.5,

182.5, 188.5, *, *, 205.5, 211.5, 217.5

The cycle repeats after 223 synodic months; that is, after 18 years, 11 (10) days, 8 hours assuming the 18 years includes four (five) leap years.

Total lunar eclipses last up to 1 hour 44 minutes. Partial lunar eclipses are as long as 4 hours.
