Create a date

importance: 5

Create a Date object for the date: Feb 20, 2012, 3:12am. The time zone is local.

Show it using alert.

The new Date constructor uses the local time zone. So the only important thing to remember is that months start from zero.

So February has number 1.

Here’s an example with numbers as date components:

//new Date(year, month, date, hour, minute, second, millisecond)
let d1 = new Date(2012, 1, 20, 3, 12);
alert( d1 );

We could also create a date from a string, like this:

//new Date(datastring)
let d2 = new Date("2012-02-20T03:12");
alert( d2 );
