Conversion number between month (synodic) [mo] and year (sidereal) [a, y, or yr] is 0.08084893788505. This means, that month (synodic) is smaller unit than year (sidereal).
Switch to reverse conversion:
from year (sidereal) to month (synodic) conversion
| [mo] |
Result in year (sidereal)
?If conversion between month (synodic) to second and second to year (sidereal) is exactly definied, high precision conversion from month (synodic) to year (sidereal) 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.
