The International Date Line is the meridian that separates two consecutive calendar days. Of course, since the line is mainly across open ocean, you can't see it.

This situation actually happened to Magellan's crew when they returned home after their circumnavigation of the earth. If your cruise should take you across this imaginary line, our staff will let you know the exact time one day turns into another - just in case you want to celebrate.
