Batman had his day (or days) on 23rd July 2014, 26th September 2015 and again on 17th September 2016. Now it's Wonder Woman's turn.
DC announced via twitter and facebook that Wonder Woman day will be 3rd June this year. Just in time for her feature film!
Nothing else has been said about the day. Maybe it's to make up for her nonsensical removal as UN ambassador, or part of her 75th anniversary, or maybe for her debut solo film, but this should be exciting.
