CST is Central Standard Time. CDT is Central Daylight Time. CT is Connecticut, but some people mistakenly use it as an abbreviation for Central Time. Daylight Saving Time begins and ends on dates set by law. Nationally, in 2012, it begins on March 11 at 2:00am and ends on November 4 at 2:00am, but states and regions may or may not choose to go along, so it is very important to use the full three letter abbreviation. Use CST when referring to time in the central time zone when and where Daylight Saving Time is not in effect. Use CDT when referring to time in the central time zone when and where Daylight Saving Time is in effect. Use CT to refer to Connecticut, or any number of other things abbreviated CT, but NEVER to identify a time zone, unless your goal is to confuse people.

Use CST (Central Standard Time) when referring to the time in the Central Time Zone when Daylight Saving Time is not in effect. Use CDT (Central Daylight Time) when Daylight Saving Time is in effect in the Central Time Zone. Use CT as a general abbreviation for Central Time without specifying whether it is standard or daylight time.

∙ 12y agoCDT means Central Daylight Time while CST means Central Standard Time. The difference is that CDT is used while Daylight savings is in effect, therefore in the summer. CST is used in the winter. In Canadian Providences Ontario (a few communities) and Saskatchewan (most), CST is used all year.

∙ 12y agoCDT is Central Daylight time - so in spring forward, 12:00 becomes 1:00.
MST is Mountain Standard time - which is one time zone earlier than Central, 12:00 becomes 11.
So the difference is 2 hours.
