Why are the British donning Red Flower Pins?
It is either ANZAC DAY or ARMISTICE DAY both are in Remembrance of World War I. ANZAC DAY is a national day of remembrance in Australia and New Zealand, originally commemorated by both countries on 25 April every year to honour the members of the Australian and New Zealand Army Corps (ANZAC) who fought at Gallipoli in the Ottoman Empire during World War I. It now more broadly commemorates all those who served and died in military operations for their countries. ARMISTICE DAY overlaps with Remembrance Day and Veterans Day and is celebrated on the day of every year on 11 November to commemorate thearmistice signed between the Allies of World War I and Germany at Compiègne, France, for the cessation of hostilities on the Western Front of World War I, which took effect at eleven o'clock in the morning-the "eleventh hour of the eleventh day of the eleventh month" of 1918. While this official date to mark the end of the war reflects the ceasefire on the Western Front, hostilities continued in other regions, especially across the former Russian Empire and in parts of the old Ottoman Empire. Wearing of the Red Poppy used to be common in the USA as well on November 11th but now that the holiday has been broadened to be a generalized '"Veteran's Day" for any Vet regardless of service in combat or any war, they tend to skip the Poppy which was once a universal symbol of the fallen of World War I AKA The Great War. The Red Poppy has fallen out in favor of more typical American Patritoic sumbols such as the Flag and the colors red, White & Blue. In The UK and Countries that are part ofthe former british Empire, they still wear the Red Poppy.
