Definition of month (Gregorian average) unit: = 30.436875 d. Average Gregorian month is calculated from average Gregorian Year divided by 12 month: 365.2425 days / 12 months × 86400 sec ≈ 2.6297 Ms
Definition of year (Julian) unit: = 365.25 d average. The basic calendar year has 365 days, but in fact the Earth needs a little more time around the sun. The Julian calendar compensated this with leap year (every fourth year had 366 days). According to the formula, a Julian year has 365 + 1/4 = 365.25 days. But even with this compensation, the astronomical year slip 0.78 days every 100 years into real seasons. Therefore, most countries have moved to the Gregorian calendar introduced in 1582.
