.... I can not tell you for sure the time it takes, I am not an expert on cider. If you want it to ferment out completely dry, it may be best to take a gravity reading when you think it is done... and then take another reading or two a few days after. If the reading stays the same it may be safe to consider fermentation is complete.
That is if you want it to ferment out. As far as I know, it seems there are other options when getting into cider that someone more knowledgeable will have to suggest to you. Until then, keep looking around on the cider threads... there is a lot of information and it can be overwhelming but you should still be good being 2 weeks. Cider seems to take time.
Good luck!
