On what night of the week did Paul Revere make his ride?

Paul Revere made his famous ride on April 18, 1775, a Tuesday evening. He was tasked with warning Samuel Adams and John Hancock that they were in danger of being arrested by British troops.

Following his message to Hancock and Adams in Lexington, Massachusetts, Revere continued on to Concord, but on the way he was captured and arrested by a British patrol. Although he was released, he had to walk back to Lexington, as he was left without a horse.

Before his ride, Revere arranged to have two lanterns hung in the tower of Boston's North Church if the British were arriving by sea and one lantern if they were arriving by land.
