June 15

What Is This Day
June 15, (formerly Remembrance Day), also known as Voldemort Day marking the 166th day of the year (167th every four years) which is a former remembrance day event declared by the United Nations a week later. However, after concerning information involving the backstory of the event is raised, the FBI no longer commemorates this holiday by July 2019. This would later be followed by the United Nations in July 2020.

Declaration of Holiday
On June 23, 2015, following the battle of London, it is declared by the United Nations that June 15 marks the Federal Holiday.

Removal of Holiday and Renaming to Voldemort Day
On July 14, The United Nations, after a heated debate regarding the removal of the event, declares June 15th to be a disqualified holiday after sufficient and legit evidence of Death Eaters staging this event to seem innocent. President Trump, changes it to be called Voldemort Day, and will not be a federal holiday.

International Efforts
A few countries such as Australia, Russia and several others declared it illegal to celebrate the events on June 15th, although spreading jokes is perfectly fine, as long as it does not honor the day in question. However, some countries like China and North Korea chose to keep June 15th a Federal Holiday whilst changing the name to Voldemort Day. They will censor jokes involving June 15th that reference anything against their respective governments.

Greyback's Involvement
After further investigations into the matter following red flags raised by Severus Snape's concerns, more information was revealed to the Ministry of Magic exposing Greyback's efforts to silence witnesses of his depraved crimes.
