One thoughtful and personal gift idea for your astrology-loving grandpa could be a detailed birth chart reading. You could find a reputable astrologist online who could create a detailed report customized to your grandpa's birth date, time, and location. Additionally, you could also combine this gift with a beautiful astrology-themed coffee table book, such as "The Secret Language of Birthdays" by Gary Goldschneider, which pairs astrological insights with detailed personality profiles for each birth date. Finally, consider getting your grandpa an astrological journal where he can note down his thoughts, insights, and observations related to his astrological experiences.
Or you can get him a star map with the date when he was born.
