## Years

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.

## Seconds

The second has historically been defined as 1/60 of a minute or 1/86,400 of a day. The SI defines the second as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.

The second is the SI base unit for time in the metric system. Seconds can be abbreviated as *sec*, for example 1 second can be written as 1 sec.
