The '30-day month' is a bookkeeping convention, real months run 28 to 31 days. A year is about 365.24 days, not 12 × 30 = 360, so the convention loses more than five days per year. Use it for rough estimates, but switch to real calendar dates when accuracy matters.
There are several year definitions: the Julian year is exactly 365.25 days, the Gregorian calendar year 365.2425, and the tropical year about 365.2422 days. For everyday use the differences are negligible, but they matter in astronomy, the light-year, for instance, is defined using the Julian year.
