Of course the language is not precise but the thing is what people understand out of a given expression. At least here, when people put a sign in a shop saying they'll be on holidays from August 1st to August 15th people understand that both are included. And it seems that all the feedback we all get is that current behaviour is not what the user expects. So for me, it is better to make closed intervals because it will make the application more predictable.

Well, that probably depends if you need to think more on the number of days of a month or what is the next month ;) Actually, the thing is probably that I'm also more used to closed intervals because that's what I've always seen (except with some rare modules in OpenERP where I always had to explain users that the behaviour of the application in there was strange...) > > -- > Cédric Krier - B2CK SPRL > Email/Jabber: cedric.kr...@b2ck.com > Tel: +32 472 54 46 59 > Website: http://www.b2ck.com/ -- Albert Cervera i Areny Tel. 93 553 18 03 @albertnan www.NaN-tic.com
