An average solar month is around 30.44 days, which is approximately one-twelfth of a solar year, which is about 365.24 days.
The period of difference between a solar year (365 days) and a lunar year (354 days) is roughly 11 days. This is why lunar calendars (based on the moon's phases) need to add intercalary months to stay in sync with solar calendars (based on Earth's orbit around the sun).
