Facebook's On This Day feature is a nostalgia machine, seemingly created to send you clicking through years-old photos of college parties or pining over your ex. Because of that emotional heft, Facebook has introduced some new filters to the tool, so that you can make sure to block certain memories from your notifications. Here's how to do just that:
If you have On This Day activated, look under Apps on your left-hand sidebar—On This Day should be near the top. Select it, and you'll be taken to a feed of throwback Facebook moments. On the right-hand side near the banner image, you'll see Preferences—choose that.
A box will surface, allowing you to filter out people and dates from the content that On This Day will show you. There you go: A little eternal sunshine for your spot-filled mind.
