I don't think that I need to store them. It would allow me to use a simple loop later on and hide the ugly things somewhere else.

Sounds like a good idea. 

I am actually reinventing the wheel because most of the functionality already is in the Calendar package. I tried to understand how this package works but there are few intermediate steps which I don't get. IE: Time_Rep? And there are others. They are probably required for managing one special problem which happens once a century.

At least I will perhaps learn why the package has been designed like this.

Thanks
