Excluding the time in a "date/time" parameter for SSRS reports

Depends on type of IDE you use, you may NOT be able to use some of those suggested methods. This always work for me: Set parameter type=TEXT instead of Date/Time, then on query convert your date as follow: SELECT Value=Convert(varchar(20),payperiod,101)

Instead of using =Now() you can use =Today() which provides current date without time .If you are getting data from DB then you can

=Format(Fields!YourDateColumn.Value,"dd/MM/yyyy")

Check this MSDN article for using expressions and formatting the date time column
