Why are Easter and Passover not close to each other this year?

Question

My very vague understanding is that the two celebrations are related because the Last Supper was a Passover Seder. With that in mind how come Easter is occurring nearly a whole month before Passover this year?

To add even more confusion, orthodox Christian religions like Greek Orthodox churches put Easter at a different time too. They use the Julian Calendar to figure when it is (May 5 this year) instead of the Gregorian calendar the rest of the world uses.
