(b) in the EXSLT library - www.exslt.org

> Hi

> can anyone help in the manipulation of dates?
> 
> What I am trying to do is subtract a number of days from a 
> date value (e.g.
> 2003-01-22 [yyyy-mm-dd]) based on a  condition (typically 
> "if" or "choose").
> The number of days subtracted will be another condition.
> 
> I must also ensure that the date I return is a valid business 
> day (Monday to
> Friday).
> 
> Does anyone know of anyway / function I could use?

> Thanks.
