    Date.prototype.setDate()

    Summary

    The setDate() method sets the day of the Date object relative to the beginning of the currently set month.

    Syntax

    dateObj.setDate(dayValue)

    Parameters

    dayValue
    An integer representing the day of the month.

    Returns

    The value returned by setDate() is the number of milliseconds since 1 January 1970 00:00:00 UTC of the resulting date (the Date object is also changed in place).

    Description
