Where diff is the difference in minutes you want from oldDateObj's time. This is like chaos's answer, but in one line: var newDateObj = new Date(oldDateObj.getTime() + diff*60000) For example, with Moment.js, this is simply: var newDateObj = moment(oldDateObj).add(30, 'm').toDate() The default is 0 milliseconds past the second.If you are doing a lot of date work, you may want to look into JavaScript date libraries like Luxon, Day.js, or Moment.js. Integer value representing the millisecond segment of a time. Note that this modifies the date object and returns the time value of the updated. The default is 0 seconds past the minute. Try something like this: var d new Date() d.setDate(d.getDate()-5). Integer value representing the second segment of a time. Integer value representing the minute segment of a time. Integer value between 0 and 23 representing the hour of the day. Integer value representing the day of the month. Integer value representing the month, beginning with 0 for January to 11 for December. Values from 0 to 99 map to the years 1900 to 1999. For example, new Date(2020, 5, 0) will return May 31st, 2020. A date (day of month) is represented by an integer from 1 to 31 in the usual. Similarly, if any parameter underflows, it "borrows" from the higher positions. It allowed the interpretation of dates as year, month, day, hour, minute. ) and the desired time to initialize two dates var date1 new Date (2000, 0. Therefore, new Date(1990, 12, 1) will return January 1st, 1991 new Date(2020, 5, 19, 25, 65) will return 2:05 A.M. Subtract JavaScript Date objects to get their difference: // use a constant date (e.g. For example, if a monthIndex greater than 11 is passed in, those months will cause the year to increment if a minutes greater than 59 is passed in, hours will increment accordingly, etc. If any parameter overflows its defined bounds, it "carries over". The parameter values are all evaluated against the local time zone, rather than UTC. Any missing fields are given the lowest possible value ( 1 for day and 0 for every other component). Given at least a year and month, this form of Date() returns a Date object whose component values (year, month, day, hour, minute, second, and millisecond) all come from the following parameters. Individual date and time component values Otherwise, the resulting primitive is further coerced to a number and treated as a timestamp. If the result is a string, it will be parsed as a date string. E’ un modo semplice di rappresentare una data. All other values are converted to primitives. Il numero di millisecondi passati da questa data vengono detti timestamp.

When one parameter is passed to the Date() constructor, Date instances are specially treated. If a parameter you specify is outside of the expected range, setMonth () attempts to update the date information in the Date object accordingly. Creating Date Objects Date objects are created with the new Date () constructor.

This is equivalent to new Date(dateObject.valueOf()), except the valueOf() method is not called. JavaScript Date Output By default, JavaScript will use the browser's time zone and display a date as a full text string: Fri 09:45:55 GMT-0800 (Pacific Standard Time) You will learn much more about how to display dates, later in this tutorial. This effectively makes a copy of the existing Date object with the same date and time. Date object dateObjectĪn existing Date object. You are therefore also advised to make sure the input format is consistent between the two types. When we want to set or get date value that time we are used javascript date methods. "") are treated as UTC, while date-time strings (e.g. The data is days before today, yValue ,yValue So i have done this where i send the days before today and i format xAxis, the problem as i said is that the points are with 1day interval and i want to make it 1 minute or 1 hour interval. A library can help if many different formats are to be accommodated.ĭate-only strings (e.g. Support for RFC 2822 format strings is by convention only. Pass the result of the subtraction to the setDate () method.

Note: When parsing date strings with the Date constructor (and Date.parse, they are equivalent), always make sure that the input conforms to the ISO 8601 format ( YYYY-MM-DDTHH:mm:ss.sssZ) - the parsing behavior with other formats is implementation-defined and may not work across all browsers. If a parameter you specify is outside of the expected range, setMinutes () attempts to update the date information in the Date object accordingly.
