Final answer:
The pilgrims in Chaucer's The Canterbury Tales began their journey in April. Separate from Chaucer's narrative, the Mayflower voyage began in July, 1620.
Step-by-step explanation:
The travelers began their pilgrimage to Canterbury in April, a detail that is famously noted in the opening lines of Geoffrey Chaucer's The Canterbury Tales. However, your question also touches upon the voyage of the Mayflower, which was a different historical event that occurred in 1620. The Mayflower journey began in July, 1620, and the Pilgrims eventually settled in Plymouth in December of the same year after a long voyage across the Atlantic.
