November 11th, known as Remembrance Day, is observed in many countries to honor the members of the armed forces who died in the line of duty during World War I and subsequent conflicts. The date marks the armistice that ended the war in 1918, and ceremonies are held to remember those who sacrificed their lives for their country. On this day, people often wear a red poppy flower, symbolizing remembrance, and participate in moments of silence at 11 a.m. Various events, including parades and memorial services, take place to pay tribute to veterans and promote peace.
