When the Clock Changes

Spring
  • 2:00 becomes 3:00, so
  • At the same time of day, the clock reads one hour later:
  • If the clock reads 4:00, then, at the same time of day before the change, it read 3:00.
  • The same clock reading now denotes an earlier time of day.
  • We lose an hour, so
  • We get one less hour of sleep.
  • Clockwise, we pray one hour later, so
  • To pray Fajr on time, you wake up one hour later.
  • If you don't change your clock, you arrive at events one hour late.
  • Going to work in the morning, you find less sun light.
  • Going home at the end of the day, you get more sun light.

Fall
  • 2:00 becomes 1:00, so
  • At the same time of day, the clock reads one hour earlier:
  • If the clock reads 4:00, then, at the same time of before the change, it read 5:00.
  • The same clock reading now denotes a later time of day.
  • We gain an hour, so
  • We get one more hour of sleep.
  • Clockwise, we pray one hour earlier, so
  • To pray Fajr on time, you have to wake up one hour early.
  • If you don't change your clock, you arrive at events one hour early.
  • Going to work in the morning, you find more sun light.
  • Going home at the end of the day, you get less sun light.
