The history of the International Date Line dates back to the Christian era 1522, when Magellan's crew reached home after circumnavigating the world for the first time by ship. They thought it was 5th September but actually they reached on 6th September. Why was it happened?
Answer
This happened because Magellan’s crew had unknowingly crossed the 180° meridian during their journey. When a ship travels around the world and crosses this line from west to east, it gains a day due to the 24-hour time difference on either side of the 180° meridian. So, although they believed it was 5th September, the actual date was 6th September.
