Conversion number between year (leap) [a, y, or yr] and month (synodic) [mo] is 12.393928205855. This means, that year (leap) is bigger unit than month (synodic).
Switch to reverse conversion:
from month (synodic) to year (leap) conversion
| [a, y, or yr] |
Result in month (synodic)
?If conversion between year (leap) to second and second to month (synodic) is exactly definied, high precision conversion from year (leap) to month (synodic) 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 (leap) unit: = 366 d. Leap year has 366 days. The role of leap year is to compensate difference from astronomical- and common calendar year.
Definition of month (synodic) unit: ≈ 29.530589 days. Synodic month = Cycle time of moon phases (example, from fool moon to next fool moon). This period is not constant and it is longer than moon rotation around Earth (sidereal month), because moon and Earth moves together around the Sun.
