Easter and Pesach (Passover) often don't co-incide.

Our calender is lunar based, but is worked out different, and during our leap years we have an extra month (Adar II), so it would be an extra 29 or 30 days later.

I think my dates might be a tiny bit off, but the Rabbi said today that Pesach can fall anytime between the 3rd of March and the 25th of April, or close to it.

Infact, i think it was 2 years ago, or last year (had to be one of them, cos i was def. married), our holiday that falls 30 days before Pesach, the festival of Purim (story of Queen Esther for those that will know what i'm talking about), fell on or just after Good Friday, cos i remember having to buy everything before the shops were shut.
