Maundy Thursday or Holy Thursday commemorates the last day of freedom for Jesus Christ. The Man from Nazareth spent his final hours of liberty with his apostles and at this Last Supper the Messiah predicts his betrayal. The date for Holy Thursday has been argued by scholars for centuries, but is generally conceded to have occurred between 30-36 AD in the Jewish month of Nisan, which would make it in April. According to Wikipedia Annie Jaubert argued that the Last Supper took place on the evening of Wednesday 1 April 33.
There was no April Fool’s Day back then.
And what was awaiting Jesus of Nazareth was no joke either.
