How about giving your dad a membership to a historical society or cultural center that offers lectures and talks? Alternatively, you could purchase him an online course or lectures related to cultural history that he can do at his own pace. Another idea could be to book him tickets to an upcoming cultural history lecture or conference. If your dad has a favorite cultural history book, you could consider getting him a special edition or a signed copy. Finally, consider taking your dad to visit a cultural history site or museum that aligns with his interests.
Or you can get him a star map with an important date you share.
