CST and CDT — US Central Time

The live current time in US Central Time, and what the abbreviation actually means. CST and CDT are the winter and summer halves of the same zone, which is why a bare CST label is ambiguous for half the year.

CST is Central Standard Time, UTC−6. CDT is Central Daylight Time, UTC−5. US Central Time uses CST in winter and CDT in summer, switching on the second Sunday in March and the first Sunday in November.

Other Meanings

  • CST can also mean China Standard Time (UTC+8) — see the current time in Beijing.
  • CST can also mean Cuba Standard Time (UTC-5), which becomes CDT in summer.
