## Calculating a new date by adding a variable to an existing date avoiding weekends

Hi,

I'm trying to calculate an 'end date' by taking a 'start date' from a form response and adding a form response 'duration' (in days). However, I wish for the calculation to avoid weekends. So, for instance if the 'start date' from the form is Friday 5th Jan and 'duration' is "2" (days) then the returned 'end date' (avoiding weekends) would be Monday 8th Jan.

So far I have managed to set the flow to take the returned date, recompose it to UK format, then add the returned duration days. I now need it to add extra days to the duration (or not) depending on whether or not the start/end dates land on a weekend. I've seen other solutions to similar cases, but none exactly matching what I need to achieve.

Here's the section of my flow so far:

(the above returns the start date for response)

(the above converts the duration form response to an integer - not sure if this is entirely necessary?)

(the above adds the duration (now an integer) to the start date, resulting in an 'end date'

Start date + Duration = End date.

What further steps can I add to ensure the start and end dates skip over weekends?

Hi Bof. Thanks you for that. It works fine if the EndDate lands on a Saturday or Sunday. In those cases the extra days are added and everything works out. However, if the EndDate lands on, say, the Monday (with the Friday being the Start Date) then it does not add the extra days.

Example: I want to make a 4 day booking, starting on the Friday, but not including the weekends. This should make the EndDate the following Wednesday (the 4 days includes the Friday, Mon, Tues and Weds).
