What's the timezone history of Saint John?

Saint John observes Atlantic Time at UTC-4 in winter and UTC-3 in summer with the federal DST schedule. New Brunswick uses Atlantic Time, the same as Nova Scotia and Prince Edward Island. The province sits at the western edge of the Atlantic zone in terms of longitude (Saint John is around 66 degrees west), leaving wall time ahead of mean solar noon by around 16 minutes in standard months. Newfoundland and Labrador uses a half-hour-offset Newfoundland Time at UTC-3:30, the only Canadian province using a 30-minute offset.

What are the working hours in Saint John?

The Irving Oil refinery (the largest in Canada), port operations, paper and pulp production, and a substantial healthcare workforce anchor employment. Office hours run 08:30 to 16:30. The substantial private-company concentration of the Irving family interests (oil, forestry, shipping, media, hardware retail) gives Saint John an unusual corporate-economy structure. The Saint John River and surrounding industrial estuary support both petrochemical and shipping operations. New Brunswick Day (first Monday of August) is the principal provincial summer holiday alongside the federal calendar.

Where is Saint John?

Saint John sits at the mouth of the Saint John River on the Bay of Fundy in southern New Brunswick, the largest city in the province. The city proper holds around 70,000 residents and the wider Greater Saint John area roughly 130,000. The city's harbour experiences the extreme tidal range of the Bay of Fundy, with around 8 metres difference between high and low tide. The Reversing Falls (Reversing Rapids) phenomenon, where the tide forces the river to flow upstream twice daily, occurs at the river's mouth. Halifax lies around 270 kilometres south-east across the Bay of Fundy.
