Calvin,
Try the term " Long Term Almanac ". You should get many results.
There are books sold at many bookstores good for 50 years, there are long term almanacs in several books that are free and down loaded from the internet ( HO 249 is one ). A very good one was written by a NavList member, Geoffrey Kolbe.
The data is usually for the sun and GHA Aries ( used for stars ). I do not think they are good for the moon or planets - I may be wrong.
