Question

Why the international date line deviates and goes zig -zag near some islands in Pacific Ocean​

Answer 1

Explanation:

For parts of its length, the IDL follows the meridian of 180° longitude, roughly down the middle of the Pacific Ocean. To avoid crossing nations internally and splitting apart countries in to two days, the line deviates around the far east of Russia and then around various island groups in the Pacific.
