BUSINESS INSIDER UK - Feb 1 - Dating app Happn says its most active day in the US is February 7, one week before Valentine's Day. This makes sense, in a slightly depressing way. People don't want to have a first day on Valentine's Day. A second date on Valentine's Day seems much more reasonable. Happn also saw a spike in the week after New Year's. New year, fresh start in finding a soul mate, it seems.
