Question

I want to know when is the New Month. So that I can do some operation
like, copy last month data [eg. Category.Title] from last month [Jan] to the new month [Feb].

Month  Catagory
=====  ========

Jan => Category.Title 
Feb => New Category.Tile (copy based on Jan's data)

How do I construct the logic to detect that Today is a new month (so that I can preform the copy operation)?

Basically, I want to detect when is the New Month begin?

Answer 1

If all you need is the logic to check if today is the first day in a month, you can use the following code.

var d:Date = new Date();
if (d.date == 1) {
    //today is the first day in a month
}

Depending on where/when you’re doing this however, it may not have the effect you desire. Without more information, I can’t really help you there.
