Thank you for this elaborate version with a completely different approach, translating week tables into a more than complex if-then-else sequence. The formula in the weeknumber routine looks interesting as well.

Thanks Dieter,

the first time i saw this formula, I immediately thought to the GREAT WP34s and its JDN function.

the weeknumber formula was found here:
http://www.auduteau.net/calendar/cal5.shtml ( in french Sorry ! )
But it seems to be the translation of (in english):
http://www.tondering.dk/claus/cal/week.php
(unfortunately where the weeknumber formula has disappeared... And has been remplaced by another formula (the author trial ? - That in some cases don't gives the good answer).

Regards,

Damien.
