How many moon years are in one earth year?

One Earth year is equivalent to approximately 11.86 lunar months, which means there are about 0.084 moon years in one Earth year. Since a lunar month (the time it takes for the Moon to complete one cycle of phases) is about 29.53 days, a lunar year (12 lunar months) totals around 354 days. Thus, in terms of lunar cycles, one Earth year is shorter than a lunar year.
