佳·福克斯之夜，又稱佳·福克斯之日或篝火之夜，是每年11月5日在英國主要舉行的紀念活動。它的歷史始於1605年11月5日美國的事件，當時火藥地塊的佳·福克斯（Guy Fawkes）被捕，當時他守衛着密謀炸藥放置在上議院下方的炸藥。慶祝詹姆斯一世國王倖免於難，人們在倫敦周圍點燃篝火。數月後，《 11月5日紀念法案》的出台，紀念推翻英皇失敗的感恩。
2006年的電影《V煞》，對政府壓迫人民的寓言，使佳·福克斯（V煞）面具成為一個用來抗議暴政的標誌。
網民今晚在尖沙咀舉行V煞面具日。晚上8點，逾千人聚集在市政局百周年紀念公園，戴上V煞面具，高呼「五大訴求，缺一不可」和「香港人，抵抗」。他們讀了宣言，唱着「榮耀歸香港」，於晚上8:30迅速散去。
Guy Fawkes Night, also known as Guy Fawkes Day, Bonfire Night and Firework Night, is an annual commemoration observed on 5 November, primarily in the United Kingdom. Its history begins with the events of 5 November 1605 O.S., when Guy Fawkes, a member of the Gunpowder Plot, was arrested while guarding explosives the plotters had placed beneath the House of Lords. Celebrating the fact that King James I had survived the attempt on his life, people lit bonfires around London; and months later, the introduction of the Observance of 5th November Act enforced an annual public day of thanksgiving for the plot’s failure.
Popularised by the 2006 movie “V for Vendetta”, an allegory of oppression by government; the Guy Fawkes mask has now become a common brand and a convenient placard to use in protest against tyranny.
Netizens planned a V-mask Day today targeting Tsimshatsui. Over 1,000 gathered with V-mask at Urban Council Centenary Garden at 8 pm and chanted “5 Demands, Not One Less” and “HongKongers Resist”. They read their declaration, sang “Glory to Hong Kong and dispersed quickly at 8:30 pm.
