Lesson details
Key learning points
- West of the Prime Meridian, you ‘lose’ four minutes for every degree of longitude, and east you ‘gain’ four minutes.
- The International Date Line is 180˚ east and 180˚ west of the Prime Meridian and is the place where the date changes.
- Meridians are the basis for the 24 time zones; many deviate from the meridian to accommodate national/state borders.
- The Antimeridian forms the basis of the International Date Line, with some deviations for national borders.
Keywords

Common misconception
Children my believe that a country's time zone is fixed and cannot be changed.
Countries occasionally change their time zone for practical or political reasons. For example, in 2024, Kazakhstan moved from using two time zones to observing only one times zone across the whole country: UTC+5
