CANADIAN TIME ZONES
CANADIAN CREATOR
• In 1858, as the chief engineer of the
Northern Railway, he proposed the idea of
a great rail project stretching to the
western coast of Canada.
• In order to help the transcontinental train
run on time, he devised the concept of
Standard Time and splitting the world into
24 time zones. His concept was adopted
in 1884.
YOU DO THE MATH!
• WORLD IS ROUND
360 degrees (longitude)
• There are how many hours in a day?

• So how many degrees wide is each time zone?
360 / 24 = ? Degrees
15 degrees
Time Zones- A
Time Zones-B
Time Zones-C
Do you see a difference?
Why does Saskatchewan not change their time from summer to winter?
The time zone boundary cuts their province in half.
Why would northeastern BC not change their time from summer to winter?
They do business on both sides of the border, so they stay with one time.
How do you remember them?
