What We Can Learn About Love From Twitter

Weddings, break-ups and which country tweets "I love you" the most.

Just in time for Valentine's Day, Twitter has sifted through its trove of billions of tweets sent in the past year to pull out some lessons about life, love and relationship milestones.

Twitter's "Calendar of Love" reveals that people tweet most about first dates in January but have their hearts broken in March. Not surprisingly, July is the most frequent time for weddings, while the most tweets about engagements are in August.

Perhaps there's something about having all of your friends settling down, because August is also the most popular time for people to discuss online dating on Twitter. December is when divorce is most tweeted about.
