About Time in Prince Edward Island

A Clock Legally Defined to the Second

Prince Edward Island once wrote its own local time into law with unusual precision. The Interpretation Act of 1939 defined the Provincial Clock in Charlottetown as running exactly 12 minutes and 29 seconds behind the time at the 60th meridian west, the reference line the entire Atlantic time zone is built around.

That figure is not arbitrary. Working the math backward, 12 minutes and 29 seconds of time corresponds to just over 3 degrees of longitude, which places the legally defined Provincial Clock almost exactly at the site of the Coles Building in Charlottetown, today known as the Law Courts Building. In effect, the law pinned the island's official time to one specific building rather than to a rounder, more general reference point.

The gap is still real today. Because the Atlantic time zone is anchored to the 60th meridian, which runs close to the zone's eastern edge near Cape Breton, sunrise in Charlottetown consistently lands a little later than in communities further east even though both share the exact same clock time.

The Island That Faked Daylight Saving for Decades

Long before Prince Edward Island adopted real Daylight Saving Time, it ran its own homemade substitute. For years, provincial government offices simply opened and closed an hour earlier each summer, a practice known locally as Advanced Summer Hours, while the clocks on the wall never actually moved.

Most businesses and residents across the island followed the same informal shift, setting personal watches ahead for the season even though the official time never changed. Public events were scheduled accordingly. When Prime Minister John Diefenbaker visited Charlottetown in May 1962, his rally was advertised for nine o'clock Advanced Summer Hours, a wording that would have meant nothing anywhere else in the country.

The island only adopted genuine Daylight Saving Time in 1963, making it the last of the Maritime provinces to do so. Remarkably, the old habit never fully disappeared. Provincial and municipal offices in Charlottetown still keep a scaled down 30 minute version of summer hours today, a direct institutional echo of a workaround that predates real Daylight Saving Time on the island by years.

Consistently the Cautious Voice on Any Change

Since finally adopting Daylight Saving Time last among its neighbors, Prince Edward Island has kept the same instinct whenever the idea of changing the system comes up again: wait for the rest of the Maritimes to move first.

In 2020, when New Brunswick and Ontario were actively discussing permanent Daylight Saving Time, Premier Dennis King said he was interested in the conversation but would not take Prince Edward Island in that direction without input from the other Maritime provinces. Two years later, meeting with the other Atlantic premiers in person for the first time since the pandemic began, King repeated the same position almost word for word, saying any move to permanent time would have to happen collectively across the region rather than province by province.

That pattern, real change eventually, but never as the first mover, has held for Prince Edward Island since long before the current round of debate, stretching back to its late and reluctant adoption of Daylight Saving Time itself in 1963.
