Remembrance day or poppy day as it is commonly referred to in some countries, is a memorial day observed by British empire commonwealth nations in honor of members of the armed forces who passed away in the line of duty. This practice dates back to 1919, since the end of the first world war.
A poppy is worn to remember the fallen heroes past. In some traditions, a one-minute silence is observed on the 11th hour, on the 11th day of the 11th month. This time marks the official end of hostilities during world war 1.
Remembrance day is marked on November 11, today, lest we forget.
