Year Definition and Usage

One year is the time it takes for the Earth to complete its orbit around the Sun. There are 365 days in a year, with the exception of the leap year when there are 366.

Years can be abbreviated as yr, and are also sometimes abbreviated as y. For example, 1 year can be written as 1 yr or 1 y.
