None.

An integer representing the year for the given date according to universal time. Returns NaN if the date is invalid.

Unlike getYear(), the value returned by getUTCFullYear() is an absolute number. For dates between the years 1000 and 9999, getFullYear() returns a four-digit number, for example, 1995. Use this function to make sure a year is compliant with years after 2000.

The following example assigns the four-digit value of the current year to the variable year.

const today = new Date();
const year = today.getUTCFullYear();

• Date.prototype.getFullYear()
• Date.prototype.setFullYear()
