Question

In ActionScript, how do you get the day number at the end of the month?

• June Example

  getEndOfMonth() returns 30;

• July Example

  getEndOfMonth() returns 31;

Answer 1

In many languages, you can achieve this by getting a date value for the zeroth day of the following month, then working it out from that. So maybe try:

var d:Date = new Date(2009,7,0);
var day:Number=d.getDate();

If that doesn’t work, you can get the first day of the following month, and subtract a day

var millisecondsPerDay:int = 1000 * 60 * 60 * 24;
var d:Date = new Date(2009,7,1);
d.setTime(d.getTime() - millisecondsPerDay);
var day:Number=d.getDate();
