The date can be hard for judging close to the Date Line.

Explanation:

The world is divided into meridians, which are also used for setting up time zones. The time zones are set up on every 15 degrees of longitude. All of them can be problematic when it comes to time if we travel between time zones. This is due to that if we travel between time zones we lose or gain hours, depending do we travel east or west.

One of these lines is problematic in particular because it is not just the time but also the date that can change by crossing it. That line is the Date Line. This line is located on the opposite side of the Prime Meridian, stretching north to south across the Pacific Ocean. This is the line when each new day starts, so not just the time but the dates start here as well. Basically, by going across this line, not just an hour that can be lost or gained, but a day can be lost or gained as well.
