Traditional anniversary lists are a hardware store: paper, cotton, leather, tin. They are fine when you want an object. They are the wrong list when the thing getting fuzzy is the story.
Early years
The first year still has the meeting within reach. Write it before it becomes one sentence. A comic of how you met is a better first-anniversary gift than a gadget if the two of you still argue about the weather that day. Put the disagreement in the chapter. Do not sand it off.
Year two and three are when photos start repeating. If you are shopping those years, ask whether you are buying a second frame for the same picture.
The middle years
By five and ten, people buy jewelry because the list says so. Jewelry is good at being kept. It is bad at holding a Tuesday. If the year you are in is the year someone asks "how did you two meet" and the answer has gotten shorter, that is the year for pages.
Later on
Later anniversaries do not need a bigger object. They need the early scene where it is still specific: who spoke first, what the room looked like, which detail you do not agree on. Print that. A proposal, if it is still ahead of you or you want it retold without the restaurant noise, has its own page: the proposal comic.
Use the traditional list when you want a thing. Use a chapter when you want the day.
