About UTC and Central Time
Coordinated Universal Time (UTC) stays on a fixed offset with no daylight saving shift. Central Time (CT) covers places such as Chicago, Houston, Dallas; it uses CST in winter and CDT in summer.
Central Time is 6 hours behind UTC during CST and 5 hours behind UTC during CDT; confirm the selected date above for the exact gap. During daylight saving time, Central Time regions that observe DST switch from CST to CDT. Use the live clocks, slider, and grid above to confirm the exact local times for your date.

UTC to Chicago-style Central Time
Map Coordinated Universal Time to Midwest and Gulf Coast civil clocks when the source is an API, market feed, or warehouse system stamped in UTC. UTC is fixed. Central Time (CT) on this page follows Chicago-style rules for Chicago, Dallas, Houston, and Minneapolis: Central Standard Time (CST, UTC−6) in winter and Central Daylight Time (CDT, UTC−5) in summer. Central is 6 hours behind UTC during CST and 5 hours behind during CDT. Confirm the selected date above for the exact gap.
Subtract six hours for CST, or five for CDT. 18:00 UTC is 12:00 PM noon CST or 1:00 PM CDT in Chicago.
Office-hour mapping from UTC
Product and trading teams often need “is this UTC event inside Chicago business hours?”
- 15:00 UTC = 9:00 AM CST or 10:00 AM CDT (typical Chicago open window)
- 14:30 UTC = 8:30 AM CST / 9:30 AM CDT (Dallas morning)
- 00:00 UTC Tuesday = 6:00 PM CST Monday (or 7:00 PM CDT Monday)
- 12:00 UTC = 6:00 AM CST or 7:00 AM CDT
Pick the date so CDT vs CST is applied correctly for summer months.
Saskatchewan and year-round CST
Much of Saskatchewan stays on CST (UTC−6) year-round and never uses CDT. Those places stay six hours behind UTC even when Chicago is on CDT (five hours behind UTC). This page defaults to Chicago-style Central; confirm Saskatchewan separately when the meeting is there.
Not Mountain Time
Denver uses Mountain Time (MST/MDT), typically one hour behind Central. El Paso and parts of west Texas follow Mountain in some counties. Do not treat Denver as Central on this UTC conversion. Overview: U.S. time zones.
