My organization needs to increase the day of  SLA  breach if there is a holiday set on the company calendar on that day.

For e.g.... If the desired completion date of a task comes on a weekend (say Saturday) , then it should be extended by two days, i.e.... The desired completion date should be that of Monday .

So how do I get hold of the calendar days or company's working days so that I can compare that in a workflow .

Is it possible through point n click (by creating a workflow )or do we need to code ?

How can we find find the week number of the given date.

Thanks.
