Count Table Recs = To System Date

I need to count the records in a table with a datetime field equal to system datetime. It looks like it is trying to match time also since time is in field too. I just want to match date only. My sql is below. Does anyone have some suggestions on how to handle this?
Date from code

DateTime todaydt = DateTime.Now;

Table Data format

[cal_str_tm] [datetime] not null,
Data in cal_str_tm field - 3/27/2008 9:43:16 PM

Thanks,
Ron


ALTER PROCEDURE SP_DpCount

(

@todaydt datetime

)

AS



SELECT @total = COUNT(cal_int_id)

from dpcalldtl

where (cal_callstat != 'COMPLETED' and cal_str_tm = @todaydt)

RETURN
