April Fool

It’s April Fool’s Day which has led me to wonder what the origins of April Fool’s Day are. There is a theory that it originated from the change of the new year (originally 25th March) to January, and those who continued to celebrate the new year between 25th March and 1st April were made fun of and sent on fool’s errands. However, as April Fool’s Day seems to have been already established in England by the time the calendar change occurred, this doesn’t seem very likely. The overall conclusion is that there is no definitive answer as to the origin.
