日付を調整するための想像上の線
AI overview
The International Date Line is an imaginary line on Earth where the calendar date changes—when you cross it, the date shifts by one day. It matters because it helps the world stay synchronized with a single system for tracking which day it is, even though different places experience day and night at different times.
