Question

why international date line is not a straight line​

Answer 1

Answer:

The International Date Line is not a straight line. It goes zig-zag. In order to avoid the confusion of having different dates in the same country, the International Date Line bends and goes zig zag at the Bering Strait between Siberia and Alaska, Fiji, Tonga and in some other islands.
