A year is the orbital period of the Earth moving in its orbit around the Sun. In astronomy, the Julian year is a unit of time; it is defined as 365.25 days of exactly 86400 seconds (SI base unit), totalling exactly 31557600 seconds in the Julian astronomical year.
In relation to the base unit of [time] => (seconds), 1 Years (yr) is equal to 31536000 seconds, while 1 Sidereal Years (Sy) = 31558149.504 seconds.| 1 Years | to common time units |
