Conversion number between year (sidereal) [a, y, or yr] and octaeteris is 0.12500217761944. This means, that year (sidereal) is smaller unit than octaeteris.
Switch to reverse conversion:
from octaeteris to year (sidereal) conversion
| [a, y, or yr] |
Result in octaeteris
?If conversion between year (sidereal) to second and second to octaeteris is exactly definied, high precision conversion from year (sidereal) to octaeteris is enabled.
Since definition contain rounded number(s) too, there is no sense for high precision calculation, but if you want, you can enable it. Keep in mind, that converted number will be inaccurate due this rounding error!

Definition of year (sidereal) unit: ≈ 365.256363004 d. Sidereal year is a time taken for Sun to return to the same position with respect to the stars of the celestial sphere, approximately 365.256363 days.
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
