Queries :: Unable To Convert Text Into Date With Different System Language Settings In MS Access

I have a table in access database which contains a text field 'EDate' that stores Date value in format (12-Apr-2013). Now I want to run a sql query on that field. User will give an input date. The sql query needs to fetch me all the records from access database whose Edate is less than or equal to the user input date.

I am using DateValue function to convert my text filed Edate into date. My query is something like this:

select * from table_name where DateValue(EDate)<='user_input_date'

I am able to perform above task if the system language settings are 'English'. But if system language settings are different say Turkish, then the query fails.

I searched a lot on web and found that DateTime function compares test data with the system date time format and gives the result. Thus it fails with different language settings.
