Lauren Dugan on getting ditched:
The two peak times are during spring break, and two weeks before Christmas. We can imagine the reasons why these are the most common times people break up: spring break is a time of youthful abandon, and it might be a downer for some college students if they're tied to a relationship while partying in the sun. And two weeks before Christmas means that you don't have to go through awkward "meet the family" events throughout the holiday season with a lukewarm flame.
You're safe on Christmas Day but Monday's are the most popular day of the week. The infographic peaks just before Spring Break so obviously the data was heavily skewed stateside.
