If you move from the west of the IDL to the east of the IDL you ____________.

• A. lose a day
• B. don't experience any change
• C. experience fatigue
• D. gain a day

Answer 1

The correct option is D gain a day

The Western Hemisphere is on the East of the IDL and Eastern Hemisphere is on the West of the IDL.
If you move from the west of the IDL, to the East of the IDL you gain a day. This means that if your current date is 9th August, on moving east and crossing the IDL your date will become 8th August.
