Facebook Knows When You're About to Update Your Relationship Status

Facebook released new findings on Friday — Valentine's Day — that hints when two people are about to change their status to "in a relationship."

In the three months (or about 100 days) before a couple updates their status to make their relationship Facebook official, the social network sees a steady increase in the number of timeline posts shared between the two. In fact, posting to each other's pages will peak (1.67 posts) at 12 days before the relationships begin and when the update is officially made ("day 0") posts typically start to decline.
