Date

Back to: JavaScript

In JavaScript the Date object represents a moment in time. The Date object contains a number that represents the number of milliseconds since 1 January 1970 UTC.

The maximum dates are ±8,640,000,000,000,000 since 1 January 1970 UTC, which is April 20, 217821 BCE – September 13, 275760 CE.

toTimeString()

toTimeString is a method that returns the time, in the local timezone:

const event = new Date('August 30, 2012 22:10:20');

console.log(event.toTimeString());

"22:10:20 GMT+0100 (British Summer Time)"

getDate()

getDate() is a method that returns the date, in the local timezone:

const event = new Date('August 30, 2012 22:10:20');

console.log(event.getDate());

"30"

getDay()

getDay() is a method that returns the day, in the local timezone:

const event = new Date('August 30, 2012 22:10:20');

console.log(event.getDay());

"4"

You maybe thinking that something is wrong, 4 is not a day of the week! This is however, correct. A number is returned, that corresponds to the day of the week. It begins with Sunday, which is 0. Therefore, 4 is equal to Thursday.

getHours()

getHours() is a method that returns the hour, in the local timezone:

const event = new Date('August 30, 2012 22:10:20');

console.log(event.getHours());

"22"

The result is in 24hr, therefore the range of possible values is 0 – 23.
