Timezones and Daylight Savings

Sarnia-Lambton is situated in the Eastern Time Zone (ET). Specifically, it is Eastern Standard Time (EST) when observing Standard Time (Winter), and Eastern Daylight Time (EDT) when observing Daylight Savings Time (Summer). Daylight Saving Time begins on the second Sunday in March and ends on the first Sunday in November (but not in most of Saskatchewan and parts of Quebec, Ontario, and British Columbia).

The clock goes forward one hour at 2:00 AM on the second Sunday in March and back to normal time at 2:00 AM on the first Sunday in November.

Daylight Saving Time was first implemented during World War I and again in World War II to conserve energy. Germany was the first nation to adopt daylight time during World War I in 1915. Britain, parts of Europe, Canada, and the United States quickly followed suit.

By observing Daylight Saving Time we, in effect, create an extra hour of daylight in the evening. An hour in which less lighting is used and thus less electricity. Studies have shown that electricity usage drops by about 1% each day with Daylight Saving Time.
