Why is poppy day on 11th?

Poppy Day, also known as Remembrance Day, is observed on November 11th 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 anniversary of the signing of the Armistice that ended World War I in 1918. The red poppy became a symbol of remembrance due to the poem "In Flanders Fields," which highlighted the poppies growing on the battlefields. Each year, ceremonies and events are held to pay tribute to those who sacrificed their lives for their country.
