Hi Guys and Gals

I'm looking to create a custom function that I pass a date to and an integer. I want to add x days onto a date and the result date is not to be a holiday or a weekend. I've got so far myself but for some reason my function lookup is returning a 'false' when its testing if its a holiday, but only on some entries.

The holidays table is a simple 3 column table with ID, Description and Holiday (This is a date/time field).

In my test, I put Xmas day in as the start date and put holidays in for xmas, boxing day, and 1st - 4th Jan. Yet my output date comes back as 4th Jan which is a holiday.... I can't figure out why it won't recognise this is a holiday.

Attached is the database - what am I missing?

I don't know where you are located but for non-US operation you must use...

nHolidays = DCount(Expr:="[Holiday]", Domain:="[Holidays]", Criteria:="[Holiday] =#" & Format(InputDate, "yyyy-mm-dd") & "#")

 ...to get a a valid date in the holidays function.

Hi Peter,

I'm from the UK. Used that format line code and worked a charm. I had a hunch it was something format related but there's no clear documentation that states that you need to do this anywhere (that I found anyway).

Nice work anyway. Thanks :)
