Conversion number between year (sidereal) [a, y, or yr] and Metonic cycle; enneadecaeteris is 0.052630599856484. This means, that year (sidereal) is smaller unit than Metonic cycle; enneadecaeteris.
Switch to reverse conversion:
from Metonic cycle; enneadecaeteris to year (sidereal) conversion
| [a, y, or yr] |
Result in Metonic cycle; enneadecaeteris
?If conversion between year (sidereal) to second and second to Metonic cycle; enneadecaeteris is exactly definied, high precision conversion from year (sidereal) to Metonic cycle; enneadecaeteris 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 Metonic cycle; enneadecaeteris unit: ≡ 6940 d. For astronomy and calendar studies, the Metonic cycle or Enneadecaeteris is a period of very close to 19 years that is nearly a common multiple of the solar year and the synodic month. ≡ 110 mo (hollow) + 125 mo (full) = 6940 d ≈ 19 a = 599.616 Ms
