Solution
- An attempt has been made to make the IDL pass through the Pacific Ocean completely.
- Had it passed through land or some islands, the people there would have had to follow different dates and timings because dates would have been different on their eastern and western parts.
- Also, it would have been difficult to know when one crosses the IDL on land and when the date changes on the calendar.
- Therefore, the IDL is not a straight line like the 180° meridian. At places, it turns East while at other places, it turns West.
