Calculation process of conversion value

1 year (Julian) = (exactly) `(31557600) / (31556952)` = 1.0000205343026 year (Gregorian)
1 year (Gregorian) = (exactly) `(31556952) / (31557600)` = 0.9999794661191 year (Julian)
? year (Julian) × `(31557600 ("s"/"year (Julian)")) / (31556952 ("s"/"year (Gregorian)"))` = ? year (Gregorian)

Convert Year (Julian) to other unit:

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.

Convert Year (Gregorian) to other unit:

year (Gregorian)

Definition of year (Gregorian) unit: = 365.2425 d average. As the common year has 365 days, the Gregorian calendar with leap years compensate the deviation from the real, astronomical year. According to this calendar, every 4th year is a leap year, except for every 100th. But every 400th is a leap year. This means that there are 97 leap years in 400 year period. So according to Gregorian's calendar, one year has 365 + 97/400 days (average). This is not a perfect approach, but in 1000 year period, the defiation is only 0.3 days compared to the astronomical year. In the year 1582 Gregorian replaced the Julian calendar.
