# YEAR

The YEAR function returns the year part of a value. The argument must be a date, timestamp, or a valid character string representation of a date or timestamp. The result of the function is a large integer. If the argument can be null, the result can be null; if the argument is null, the result is the null value.

The other rules depend on the data type of the argument specified:

- If the argument is a date, timestamp, or valid string representation of a date or timestamp: The result is the year part of the value, which is an integer between 1 and 9 999.
- If the argument is a date duration or timestamp duration: The result is the year part of the value, which is an integer between -9 999 and 9 999. A nonzero result has the same sign as the argument.
