It’s taken years of testing, but Facebook will now be able to relive some important events from their lives using “On This Day” personal history reminders.

The tool was launched by Facebook on Tuesday and creates a dedicated page for users that filters anything from birthdays to anniversaries and notifies you of a special moment through your News Feed or through an app on your phone, a feature that has been in testing for years now, according to a Mashable report.

After receiving user feedback, Facebook finally gave the green light to go ahead and implement the new feature, which users won’t be able to opt out of, at least completely. However, the company says its algorithms will keep negative memories, such as a death of a loved one, from showing up here — a particularly sore subject after the infamous “Year in Review” feature a few months back that unwittingly cheerily reminded people of tragic events.

“On This Day” reminders won’t apply only to special events, but also to posts that you were tagged in. So if you partied hard one night, Facebook may reminds you each year. You can delete it from your News Feed, so you better hope you catch them as they happen if there’s anything you’re embarrassed about.

“On This Day” has its own set of notifications, which you can switch off. You will also have access to a private On This Day page that will allow you to delete events or dates you don’t want to crop up again.

The feature may not be initially available for some users as the company gradually distributes it to users worldwide over the next few days, according to the report.
