Up until WWII, Remembrance/Armistice Day was observed on November 11. After that, in order to reduce disruption to the working day, it shifted to Sunday and was observed by all - this was the day when the Two Minutes Silence at 11 am was observed, as well as ceremonies at local war memorials - laying of wreaths of poppies, particularly to commemmorate those whose bodies were never recovered or were buried a long way away.

Some years ago, the 11th fell on a Sunday, and since then it has become the practice to observe the Two Minutes Silence on the actual 11th again.
