) and the desired time to initialize two dates var date1 new Date (2000, 0. It's not clear what you want to do with your function. Subtract JavaScript Date objects to get their difference: // use a constant date (e.g. You start with a UTC base date other than "now", using Date.UTC() newDate = new Date(Date.UTC(2015, 3, 1)).getTime() + -5*24*3600000 There are various methods to set the date in JavaScript. Epoch time, also referred to as zero time, is represented by the date string 01 January, 1970 00:00:00 Universal Time (UTC), and by the 0 timestamp. You want the UTC date 5 days ago from NOW (UTC) var newDate = Date.now() + -5*24*3600*1000 // date 5 days ago in milliseconds UTC 1508330494000 The large number that appears in our output for the current timestamp represents the same value as above, October 18th, 2017. However, it works if you're doing your math all in UTC, egĪ. Classe DATE (suite) - Bonjour tout le monde, Actuellement en formation Cnam, je cherche une classe date pour windev. With the first method, all you need to do is change this: const day dateValue.getDate () const month dateValue.getMonth () + 1 // Return Value is 0 indexed const year dateValue. Note that this modifies the date object and returns the time value of the updated. toString() which returns the local date and therefore is incompatible with the Date.now() base date in UTC. Harder Ask the user their timezone, and specify that timezone when you save the date. Try something like this: var d new Date() d.setDate(d.getDate()-5). ![]() assume (wrongly) that Date.now() gives you the current LOCAL now time, or When you add 30 days to a JavaScript date, the setDate() method also updates the month accordingly.To expand on that, the answer above will have daylightsaving inaccuracies in the case where you want to calculate the LOCAL day 5 days ago in a timezone with daylightsaving changes and you If a parameter you specify is outside of the expected range, setMinutes () attempts to update the date information in the Date object accordingly. Step 5 Use the setDate () method to set a new date. Step 4 Get the date from the date1 using the getDate () method, and add 1. Step 3 Create a new date from date1, and push it to the dateArray. A date (day of month) is represented by an integer from 1 to 31 in the usual. ![]() For example, if you use 100 for secondsValue, the minutes will be incremented by 1 ( minutesValue + 1 ), and 40 will be used for seconds. It allowed the interpretation of dates as year, month, day, hour, minute. This way, the month 7 actually is August. Step 2 Use the while loop, and check if date1 is less than date2. If a parameter you specify is outside of the expected range, setMinutes () attempts to update the date information in the Date object accordingly. var a new Date () // noofdays is an integer value var b new Date (a.setDate (a.getDate () + noofdays) Share. The creation of the date new Date(2013, 7, 3) does not create the date 03/Jul/2013: Months are zero-based, meaning they go from 0 to 11, not 1 to 12. As s/he says "Some day in year have 23 hours, and some 25 due to timezone rules". Two methods: 1: var a new Date () // noofdays is an integer value var b new Date (a.setTime (a.getTime () + noofdays 86400000) 2: Similar to the previous method. ![]() NOTE: Date.now() doesn't work in older browsers (eg IE8 I think). ![]() So use Date.now() var newDate = Date.now() + -5*24*3600*1000 // date 5 days ago in millisecondsĪnd if you like it formatted new Date(newDate).toString() // or.
