The Christian calendar is solar, primarily due to the fact that Julius Caesar decided that it should be so back in 46 BC. Since all modern Christian denominations are derived from the "original" Roman Catholic church, it stuck.
Easter is defined as the first Sunday after the first full moon after March 22. I think. I didn't Google this, so I'm not 100% sure, but it's something like that.
