How old are the girls from W.i.t.c.h?

Question

I just read the first book (I dont know why, I hate all those 'fighting monsters' books) and they kept on going on about being teenagers. How old are they (Will, Irma, Elyon, Taranee, Hay Lin and Cornelia)? I realise some are older by a year or so than the others.
