Internet traffic - especially for a specific niche - such as dating sites, have similiar usage patterns over time.
Over christmas, traffic goes down - shortly after christmas (27th) traffic goes up - higher then before christmas as people need to "catch up".
Especially before New Year's Eve - many singles are looking for a date to celeberate the new year and traffic on dating sites goes up.
This year, I could also observe that the mobile traffic and tablet traffic was increasing after xmas - probably as many people received a tablet pc or a mobile phone as a xmas gift.
