How about a mystery experience for your wife as an anniversary gift? You could book a night out on the town that allows her to solve a mystery, such as an escape room or a murder mystery dinner. Another idea could be to create a scavenger hunt where your wife has to solve clues to discover a surprise location or gift at the end. For a more traditional approach, you could purchase her a mystery book or subscription to a mystery-themed book club.
Or you can get her a star map with the date of your anniversary.
