Daylight Saving Time

Referendum Question 2 states:

Do you want Alberta to adopt year-round Daylight Saving Time, which is summer hours, eliminating the need to change our clocks twice a year?


You may vote “Yes” or “No”

  • A “YES” vote means you support a permanent change to summer hours and no longer turning clocks forward in March and backward in November.
  • A “NO” vote means you support continuing the current practice of turning the clocks forward in March and backward in November.

What do we do now?

 Currently, Alberta changes clocks twice a year. We “spring forward” one hour on the second Sunday in March and “fall back” one hour on the first Sunday in November. This changes the time we experience sunrise and sunset.


What change is being proposed?

 The referendum question asks if you would like to remain on “summer hours”, no longer changing our clocks in March and November. This will change the time we experience sunrise and sunset in fall and winter. Our summer hours will stay the same.


Can you give me an example?

 The following table provides examples of sunrise and sunset times for different areas of Alberta. It shows the current practice of changing clocks twice a year and the proposed practice of remaining on summer hours.

Summer Hours1

 

These hours are the same in both scenarios

Winter Hours2

These are the hours we currently experience

What happens following the vote on this question?

The referendum question about daylight saving time is a non-constitutional question asked under the authority of section 5.1 of the Referendum Act. The result of the vote on this question is binding on the provincial government.

Due to the time needed to implement a change, should the majority vote “YES” on this referendum question, that change will not happen before Fall 2022. Albertans will continue to change their clocks in the fall of 2021 and the spring of 2022.
