will I get 11 months of subscription if I renew it a month later?

hi all,
I was cancelled auto-renew because I was waiting for my new computer. now that I got my new computer I would like to renew my subscription. but when I go to renewal page, it says something like "on [DATE] you will be charged [AMOUNT] ...".. and the date the page shows is a month ago, exactly my previous subscription ended..
so, if I renew my subscription, will it start a month ago? or today? will I get 11 months of subscription or will it renewed starting from today?
thanks.
