These examples always use CHOST (UTC+9) and CST (UTC-6). They stay the same when you change the date or time above. The selected conversion may differ when daylight saving time applies.

CHOST is 15 hours ahead of CST.

CST is US Central winter time (early November to mid-March). The rest of the year Chicago uses CDT (UTC-5), one hour later. For Central Time that follows daylight saving time, use CHOST to CT. For daylight-time examples, use CHOST to CDT.

How the time difference changes

For most of the year, CHOST is 14 hours ahead of CDT. From Nov 1, 2026 to Mar 14, 2027, and from Nov 7, 2027 to Mar 12, 2028, CHOST is 15 hours ahead of CST.

For most of the year, working hours of 9:00 am to 6:00 pm in CHOST correspond to 7:00 pm (previous day) to 4:00 am in CDT. At other times of the year, working hours of 9:00 am to 6:00 pm in CHOST correspond to 6:00 pm (previous day) to 3:00 am in CST.For most of the year, working hours of 09:00 to 18:00 in CHOST correspond to 19:00 (previous day) to 04:00 in CDT. At other times of the year, working hours of 09:00 to 18:00 in CHOST correspond to 18:00 (previous day) to 03:00 in CST.
