🕰️ Flash Card: Time Zones

🌍 What is a Time Zone?

A time zone is a region of the Earth that has the same standard time, usually defined by its distance (longitude) from the Prime Meridian (0° Greenwich, London).

🗺️ Key Facts

  • Earth is divided into 24 time zones.
  • Each zone covers 15° of longitude = 1 hour difference.
  • The reference line is the Prime Meridian (GMT/UTC).
  • GMT (Greenwich Mean Time) & UTC (Coordinated Universal Time) are global time standards.

⏳ Examples

  • India: IST = UTC +5:30
  • USA: Multiple zones (EST = UTC –5, PST = UTC –8)
  • Japan: JST = UTC +9

🌟 Fun Facts

  • Some countries use half-hour or 45-min offsets (e.g., Nepal = UTC +5:45).
  • China has only one time zone (UTC +8) despite its vast size.
  • Time zones help with international travel, trade, and communication.

👉 Time zones keep the world organized and synchronized despite different longitudes!
