Method of Date
Syntax
setMonth( monthValue, dayValue )
Parameters
| Parameter | Description |
|---|---|
| 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. |
Description
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.
