is the grinch a halloween show or a christmas show

i have seen the original cartoon classic about the grinch a lot of times. it is a classic and i was always wondering if it was a halloween show or a christmas show. i have seen it both times of the year and even though it is christmas time when it happens you do see things of halloween. the grinch who stole christmas with boris karloff is a lot better than the one with jim carrey. it was a timeless piece to watch every year. kind of like the wizard of oz around easter. it is kind of a tradition in my family to watch these shows.
