The following listincludes methods for accessing date values: 1. getDate(): Returns the day of the month. If you need to do date math across timezones, follow this link to a couple date/timezone tools at the bottom of this page. var start = new Date ().getTime (); Then do your processing and substract start from the current time in millseconds. First get the start timestamp as follows. You can try a good library which integrates well with MomentJS, and have good features for working with timezones.. To answer the quest, moment-timezone offers an API to change the timezone of the provided moment object, like this: This will give you the time taken between the two points in time in milliseconds. Here date difference I am calculating from January 1, 1970. While using W3Schools, you agree to have read and accepted our, A Number, representing the number of milliseconds since midnight January 1, 1970. The example formats date and time using Moment's format() function. This indicates the difference between two date-time in the specified unit. The remaining time (the difference) is calculated in milliseconds. Calculate The Number of Days Between Two Dates in JavaScript. Note that unlike many other systems, timestamps in JavaScript are in milliseconds, not in seconds. we will explain, In JavaScript how to convert hours to minutes, seconds and millisecond, how to convert minutes to seconds and milliseconds, how to convert seconds to milliseconds, how to convert date string to milliseconds in javascript. Example Returns the milliseconds in the specified date according to local time. The window object allows execution of code at specified time intervals. Notice how the year for \"Christmas\" is dynamically set to the current year (or nextyear if Christmas has already passed for this year), so the script is reusable now and in the future as well without having to modify it. $ node format.js ISO 2018-07-03T10:09:47+02:00 Time 10:09:47 10:09:47 am Date Tuesday, July 3rd 2018 2018-07-03 Localized 10:09 AM 10:09:47 AM 10:09:47 AM 07/03/2018 7/3/2018 This is a sample output.
