An anniversary example
Remember the day your story began
Imagine Maya and Theo met on January 1, 2024. Their example above uses “NGC 1232: A Grand Design Spiral Galaxy,” published in APOD on that exact date, with their names and an anniversary greeting. The photo was taken earlier; the match is to its publication date. Use a wedding, first date or friendship anniversary the same way.
