Which Side of Earth Sees the New Day First? West, Not East

Contrary to the question's premise, places farther west experience the new day first.

Why? Earth rotates west to east (counter-clockwise from above the North Pole). As it spins, the eastern edge of the daylight zone moves into sunlight first—but that means locations to the west are the first to enter a new calendar day.

Visualize It

  • Sun rises in the east → eastern locations see dawn earlier in the day.
  • But the date line (where the day flips) is in the Pacific. Moving west, you cross it sooner.
  • Example: When it's midnight Tuesday in London, it's already Wednesday morning in Tokyo (east), but still Monday in Los Angeles (west). Wait—that's wrong. Actually, Tokyo is ahead in date. The new day starts at the International Date Line (~180°), which is in the western Pacific. So the westernmost inhabited places (e.g., Kiribati's Line Islands, UTC+14) greet the new day first.

Correction: The new day begins at the International Date Line in the west. So westward locations (relative to the Date Line) see it first. The question had it backward.
