JavaScript getYear Function

JavaScript getYear is one of the Date Functions that returns the current year of a given date minus 1900. The syntax of the getYear function is:

 Date.getYear()

In this example, we use the getYear function to return the year (year – 1900) in the current date and time.

<!DOCTYPE html>

<script>
  var dt = Date();  
  document.write("Date and Time : " + dt);
  document.write("Get Year : " + dt.getYear());
</script>
</body>
</html>
Example

getYear Function Example

In this getYear example, we extract the year from the date without the year. Or, we can say, get a year from time.

<head>
    <title> JS </title>
</head>
<body>
    <h1> Example </h1>
<script>
  var dt = Date("10:12:22.0716");
  document.write("Date and Time : " + dt);
  document.write("Year  : " + dt.getYear());
</script>
</body>
</html>
Example

Date and Time : Invalid Date
