Conversion number between year (Julian) [a, y, or yr] and octaeteris is 0.125. This means, that year (Julian) is smaller unit than octaeteris.
Switch to reverse conversion:
from octaeteris to year (Julian) conversion
| [a, y, or yr] |
Result in octaeteris
?If conversion between year (Julian) to second and second to octaeteris is exactly definied, high precision conversion from year (Julian) to octaeteris is enabled.

Definition of year (Julian) unit: = 365.25 d average. The basic calendar year has 365 days, but in fact the Earth needs a little more time around the sun. The Julian calendar compensated this with leap year (every fourth year had 366 days). According to the formula, a Julian year has 365 + 1/4 = 365.25 days. But even with this compensation, the astronomical year slip 0.78 days every 100 years into real seasons. Therefore, most countries have moved to the Gregorian calendar introduced in 1582.
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
