CoffeeScript Date - setMonth()


The setMonth() method sets the month for a specified date according to local time.


Given below is the syntax of setMonth() method.

Date.setMonth(monthValue[, dayValue])

Parameter Detail

  • monthValue − An integer between 0 and 11 (representing the months January through December).

  • dayValue − An integer from 1 to 31, representing the day of the month.

If you do not specify the dayValue parameter, the value returned from the getDate method is used. If a parameter you specify is outside of the expected range, setMonth attempts to update the date information in the Date object accordingly. For example, if you use 15 for monthValue, the year will be incremented by 1 (year + 1), and 3 will be used for month.


The following example demonstrates the usage of the setMonth() method in CoffeeScript. Save this code in a file with name

dt = new Date "February 19, 2016 23:15:00"
dt.setMonth 5
