This uses Central Time as in Chicago. Saskatchewan uses CST (UTC−6) all year. Manitoba stopped changing its clocks on Nov 1, 2026 and stays at UTC−5, so in winter Winnipeg is an hour ahead of Chicago.
UTC never changes, so the gap with North American time zones shifts by an hour when they change their clocks.
UTC is 6 hours ahead of CST in winter, and UTC is 5 hours ahead of CDT in summer.
9:00 AM CST is 3:00 PM UTC in winter, and 9:00 AM CDT is 2:00 PM UTC in summer.
12:00 PM CST is 6:00 PM UTC in winter, and 12:00 PM CDT is 5:00 PM UTC in summer.
5:00 PM CST is 11:00 PM UTC in winter, and 5:00 PM CDT is 10:00 PM UTC in summer.
