<script>
document.getElementById("demo").innerHTML = Date();
</script>

Creating Date Objects

The Date object lets us work with dates.

A date consists of a year, a month, a day, an hour, a minute, a second, and milliseconds.

Date objects are created with the new Date() constructor.

There are 4 ways of initiating a date:

new Date()
new Date(milliseconds)
new Date(dateString)
new Date(year, month, day, hours, minutes, seconds, milliseconds)

Using new Date(), creates a new date object with the current date and time:

Date Methods

When a Date object is created, a number of methods allow you to operate on it.

Date methods allow you to get and set the year, month, day, hour, minute, second, and millisecond of objects, using either local time or UTC (universal, or GMT) time.
