Definition of octaeteris unit: = 2922 d. In astronomy, an octaeteris is the period of eight solar years after which the moon phase occurs on the same day of the year plus one or two days. = 48 mo (full) + 48 mo (hollow) + 3 mo (full) = 8 a of 365.25 d = 2922 d = 252.4608 Ms
Definition of day (sidereal) unit: ≈ 23 h, 56 min, 4.0916 sec. A sidereal day is the time needed for the Earth to rotate once around its axis so that the distant stars appear in the same position in the sky. This is ~4 minutes shorter than the solar day.
