Getting the weekday and weeknumber

Introduction

This is my first attempt ever to write an article of any kind. I don't have much experience in programming, but I would love some feedback about this article in order to learn. English is not my primary language, so be nice to me. :-)

Background

I'm currently working on a calendar application with a friend of mine, and knowing the weekday and the weeknumber is somehow fundamental. ;)

I can't remember where I found the algorithms and information necessary to know how to retrieve the weekday and weeknumber, but if you know, then contact me and I will give the person credits for it.

How to use CWeek

CWeek is easy to use. First, declare an instance of the object.

C++
CWeek date;

After this, you should set the date. For example, October 15, 2004.

C++
date.setDate(2004,10,15);

To retrieve the weekday or the weeknumber, simply use:

C++
nWeeknumber = date.getWeeknumber();
nWeekday = date.getWeekday();

The first week of the year is country dependent. For some it's the week containing the first day of the year, for some others the week containing at least 4 days of january and for some others it's the first full week of january.
