If it is Sunday just east of the Internatonal Dateline, what day is it just west of the Internatinal Dateline?

To determine the day just west of the International Date Line given that it is Sunday just east of the International Date Line, we need to understand the concept of the International Date Line (IDL) and how it affects time and date.

The International Date Line is an imaginary line on the Earth's surface that follows the 180° longitude meridian. It is located halfway around the world from the Prime Meridian (0° longitude) that runs through Greenwich, London, UK. The IDL is not a straight line but deviates to avoid splitting countries into two different dates.

When you cross the IDL from east to west, you "lose" a day, and when you cross it from west to east, you "gain" a day. This means that the time and date change significantly when you cross the IDL.

Given that it is Sunday just east of the International Date Line, we need to move westward to determine the day. Since we're moving in a westerly direction, we will be "gaining" a day. Therefore, it will be Monday just west of the International Date Line.

Please note that this answer assumes a typical scenario and does not take into account specific time zones, daylight saving time adjustments, or other regional factors that might affect the actual time and day.
