I say, what about a PEACE DAY. I think the UN nominated September 21st as International Peace Day but how many of us are aware of that?
I did think about a PEACE PILGRIM day in honour of the amazing woman who walked 25,000 miles between 1953 and 1981 in a personal pilgrimage for peace. She vowed to "remain a wanderer until mankind has learned the way of peace, walking until given shelter and fasting until given food". She died aged 73 in 1981. However, this is a UK Public Holiday they are polling for, so people might not consider this appropriate.
