Central Daylight Time, Central Standard Time, CDT, CST

From mid-March to early November, Central Daylight Time is observed in Manitoba and parts of Ontario and Nunavut. From early November to mid-March, Central Standard Time is in effect. The name of the time zone is abbreviated when a specific time is stated; otherwise it is written out in full. The abbreviations CDT and CST are written in upper case, with no periods. Time zones may be stated with either the 12-hour or 24-hour system (e.g. 3:15 a.m. CDT or 03:15 CDT).

• In summer, Saskatchewan remains on Central Standard Time, so when it is 6 p.m. in Saskatoon, it is also 6 p.m. in Calgary where mountain daylight time is in effect.
• If Steven left Moose Jaw at noon, he should arrive in Regina before 1:30 p.m. CST.
• All participants in Saskatoon’s Spring Fun Run must sign in before 18:00 CDT Saturday.
