  1. Mathematics for Airline Scheduling

  2. Greenwich Mean Time (GMT) • All time is measured from Greenwich a suburb of London in England. • The zero degree longitude line or the Prime Meridian passes through Greenwich. • Greenwich Mean Time (GMT) is the time it is in Greenwich. • Greenwich was chosen as a lot of the world’s sea charts were being drawn up in England at that time.

  3. Earth Rotation • 24 hours to make a complete rotation of 360 degrees • 360/24=15 • Every 15 degrees is approx 1 hour

  4. Time Zones • The earth is divided into time zones. • Each time zone has a difference in time of approx 1 hour from Greenwich. • Time zones tend to avoid land masses if possible.

  5. International Date Line • The line is at 180 degrees Longitude. • Time is on the same on each side of the line, only it is a different day.

  6. East or West of Greenwich • The earth travels west to east, hence the west is behind the east. • Add 1 hour for each time zone east of Greenwich and subtract 1 hour for each zone west of Greenwich.

  7. Example: Galway 2 p.m
