Answer:
Saturday
Step-by-step explanation:
The international date line refers to the imaginary line that starts from the north pole and extends downward to the south pole. It is the line that separates one single calendar day from the other.
Towards the west of this international date line, it is one day ahead, and towards the east of this line, it is one day behind. This means if it is Monday in the west and one crosses this line and reaches the east side, then it is Sunday in the east.
Thus, if it is Sunday in the west, then crossing the line and moving towards the east, then it is Saturday in the eastern side.
