Clutter Day is a Secular Holiday with spiritual overtones. On Clutter Day, one disposes of combustible material which has emotional significance, but no further practical use. It is the respectful way of ridding oneself of Clutter. Ideally, friends gather in a quiet natural space and burn their Clutter together.
As soon as I finish this UD definition, I will invite my friends to a Clutter Day in the (South Jersey) pines.
