I want to add 365 days to a formatted javascript date. getDate ( ) - 7 )įinally, if you are frequently manipulating dates in JavaScript, just add a function to Date’s prototype and call it directly whenever you want to add or subtract days: Date. Try it Syntax setDate(dayValue) Parameters dayValue An integer representing the day of the month. To instead change the day of the month for a given Date instance based on UTC time, use the setUTCDate () method. If adding days shifts the month or year, the changes are handled automatically by the Date object. The setDate () method changes the day of the month of a given Date instance, based on local time. ![]() const d new Date () d.setDate(d.getDate() + 50) Try it Yourself. The setDate () method can also be used to add days to a date: Example. If you use 40 for dayValue, and the month stored in the Date object is June, the day will be changed to 10. const d new Date () d.setDate(15) Try it Yourself. For example, if 0 is provided for dayValue, the date will be set to the last day of the previous month. To subtract days from a date in JavaScript, simply minus the number of days when updating date with the setDate() method: const today = new Date ( ) const lastWeek = new Date ( ) // Minus 7 Days If the dayValue is outside of the range of date values for the month, setDate () will update the Date object accordingly. You can also update the existing JavaScript Date object as shown below: const date = new Date ( ) Add days to JavaScript Date 30 answers I am using this code on the page to show when the next few dates are, they are always the next few days. The following example demonstrates how you can add 7 days to the current date: const today = new Date ( ) const nextWeek = new Date ( ) // Add 7 Days The setDate() and getDate() methods of the Date object can be used to increment or decrement days from a date in JavaScript.
