However, very rarely do we have to care about these microscopic amounts of time. In addition, you can use the setMilliseconds() method and setMilliseconds() method if needed. In the code above, we have continuously mutated the original date object by adding days, hours, minutes, and seconds to it. The example below calculates a time in the future that is 5 days, 9 hours, 30 minutes, and 30 seconds away: // Get the current dateĬonsole.log('today: ', date.toLocaleString()) Ĭonsole.log('result: ', date.toLocaleString()) Log current date and expired date in friendly formatĬonsole.log("Current date: ", currentDate.toDateString()) Ĭonsole.log("Expired date: ", expiredDate.toDateString()) ġ5 * 24 * 60 * 60 * 1000 is exactly the number of milliseconds in 15 days.Įxpired date: Fri Using getDate(), setDate(), getHours(), setHours() Show a Custom Context Menu on Right ClickĬonst expiredDate = new Date(currentDate.getTime() + 15 * 24 * 60 * 60 * 1000) Programmatically Disable/Enable a Text Input Try it Syntax setMonth(monthValue) setMonth(monthValue, dateValue) Parameters monthValue An integer representing the month: 0 for January, 1 for February, and so on. Get an array of dates between 2 given dates The setMonth () method of a Date instance changes the month and/or day of the month for this date according to local time. Sorting an Array of Objects by Date Property Truncate the time portion of a date string We can initialize a date with the given time zone by adding the time zone information to the date string we use to create the Date instance in JavaScript. Get current date time in yyyy/MM/dd HH:mm:ss formatĢ Ways to Convert a String into a Date ObjectĬonvert Timestamp to Date Time and Vice Versa So if we’re in the Pacific time zone, we get 9 since it’s Daylight Saving Time so it’s 7 hours behind UTC and 15 hours behind UTC +8.
