In 2016 the Earthworm Society of Britain (ESB) nominated 21st October as World Earthworm Day to give the world an opportunity to celebrate these ecologically vital and under-appreciated animals.

An October date was chosen in order to honor the father of earthworm ecology, Charles Darwin, as this is the month that his book ‘The Formation of Vegetable Mould Through the Actions of worms’ was published. The theme for World Earthworm Day on  Thursday 21st October 2021 will be Worms of the World.
