353, 354 or 355 days

Explanation:

A Lunar month has in average 29.53 [Lunar month - Wikipedia, the free encyclopedia].

So #12*29.53=354.36# days. In practice lunar years with 12 months will have 354 or 355 days. By rules based on religion the jewish calendar also permits years of 353 days. [https://en.wikipedia.org/wiki/Hebrew_calendar]
