so that mean anything we buy will accumulate in the statement date,
and also the interest free period actually starts frm the statement date to the due date (not from the date of purchase rite),
if like that then we can have like u said more than 40 days of interest free

,
im confused bcos before,i consult abt it with CIMB bank officer when im there,
and he kept saying that if i dont pay my usage 20 days after i swept my card for any purchases,
i will be charge with the finance charge, i dont want that..
and according to his explanation (if it is true),
then we need to know the date of every purchases we make,
and start counting the days, if we want to avoid the finance charge,
correct me if im wrong, still learning here

when u have credit card, look at
statement date,
due date and
statement balance.
i give u my hsbc bill, statement date is 28/12/2010 and due date is 17/01/2011.
so, statement date 28/12/2011 are usually swipes 1 month before (29/11/2010 till 28/12/2010), and i must pay it by 17/01/2011.
my statement balance is rm13,531.96
meanwhile, between 29/12/2010 till today, i already swipe rm3,671.94 (called as current/unbilled/recent transaction).
here, if i want 20 days interest-free period,
i must pay rm13,531.96 (full statement balance) on 17/01/2011!
so my current rm3,671.94 wont be charged with interest ~
this is what its mean with 20 days interest-free period (28/12/2010 - 17/01/2011 wont be charged with interest).
but like Gen-X mentioned,
its actually more than 20 days.
let say i swipe rm3,000 on 29/12/2001, it will be billed on 28/01/2011, and i need to pay it on 17/02/2011.
if calculated exactly,
its 51 days~ 
the bank officer should tell u in easy word, which is:
pay statement balance (NOT minimum balance) on due date and u wont be charged with any interest 
full statement balance ok! like my statement, must pay exactly 96 cents (at the back) or just pay extra such as rm13,540 (if using CDM).
if i pay rm13,530 and leave even just rm1.96, that rm1.96 and my current rm3,671.94, plus any swipe before 28/1/2011 all will have interest!
