What is the Proper formatting of date in Pervasive ODBC SELECT

I am trying to retrieve access from a Pervasive Database using Pervasive ODBC.  I want to find employees hired after a certain date.  my current query looks like:
     Employee.HireDate >= '01/01/2015'

I have also tried Employee.HireDate >= '20150101'   In either case I get the error "Error : -1 [Pervasive][ODBC Client Interface][LNA][Pervasive][ODBC Engine Interface]Error in predicate: Employee . HireDate >= '01/01/2015'  "

Can anyone help my identify the proper format/syntax of the where clause using a date?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Almost all SQL dialects allow Y-M-D format:
WHERE Employee.HireDate >= '2015-01-01'

Explicit conversion is another option:
WHERE Employee.HireDate >= CAST('2015-01-01' as DATE)

And Pervasive should also allow date literal:
WHERE Employee.HireDate >= {d '2015-01-01'}

What data type is Employee.HireDate?

Don't use such a sequence as this: 12/07/2015

Is the date I used in December? or July?

(Don't bother answering, the fact that you cannot tell for sure is the only reason for asking)

no points pl.

I had to specifically CAST the value as a date - the other two possibilities did not work.  (Just added this notes so anyone else who looke here for a solution will know which one worked.)  Thanks
