Need to know number of users login in EBS

Hi all

I need to know the number of users login between particular period

I am executed below command

select * from icx_sessions where  disabled_flag != 'Y' and (last_connect + decode(FND_PROFILE.VALUE('ICX_SESSION_TIMEOUT'), NULL,limit_time, 0,limit_time,FND_PROFILE.VALUE('ICX_SESSION_TIMEOUT')/60)/24) between to_date('01-JUN-2014','DD-MON-YYYY') and to_date('05-JUN-2014','DD-MON-YYYY');

But when I login today (4th June 2014), I could not find my session.

Kindly suggest
