Format parameter date string

I have a Analysis services dimension which is returning a date in the format
yyyy/mm/dd, I have added reporting filters (Parameters from-Date and to-Date
with datatype date to show calendar) for this date which is showing the
selected date in the format mm/dd/yyyy. How can I "format the parameter
values" or "write the expression" or "update MDX" so that the report shows
data within the filter dates?
Thanks and Regards
SridharFYI: I am using SQL Server 2005 and web-based reports using reporting
services.
