On What Days Do People Masturbate the Least?

Your favorite illicit website, PornHub, attempts to answer this
question with an interactive infographic that shows significant
traffic drops/spikes in various countries during major holidays
and other seminal events.
The PornHub graphics also compare individual countries' traffic
with worldwide PornHub surfing, underscoring the power that
holidays have in making people close that particular tab to
brave family obligations, or the opportunity to close the deal
with a real person during the NYE countdown. Or, in the case
of the Royal Wedding, they underscore how much the UK was
invested in Wills and Kate, while the rest of the world did not
care nearly as much.
