SGT ↔ CST Time Converter

Central Standard Time (CST) is 14h behind of Singapore Standard Time (SGT). SGT runs at UTC+8 and CST at UTC-6 / UTC-5 (CDT). Quick time examples: 8:00 AM SGT = 6:00 PM CST; 12:00 PM SGT = 10:00 PM CST; 5:00 PM SGT = 3:00 AM CST.

To convert SGT to CST, subtract 14 hours to the SGT time. For example, 12:00 PM SGT becomes 10:00 PM CST. When the result crosses midnight, advance the date by one day (shown as "+1 Day" in the converter). The converter on this page handles all arithmetic and date-rollover automatically.

Central Standard Time (CST) is 14h behind of Singapore Standard Time (SGT). Reversed: SGT is 14h ahead of CST. Practical example: noon in Chicago (12:00 PM CST) corresponds to 2:00 AM SGT in Singapore, and 5 PM in Chicago corresponds to 7:00 AM SGT.

Singapore Standard Time (SGT) is the standard civil time for Singapore and the surrounding region, operating at UTC+8 from UTC. It does not observe Daylight Saving Time; the UTC offset stays at UTC+8 every day of the year. Major cities: Singapore, Kuala Lumpur, Penang, Johor Bahru, George Town, Ipoh, Kuching.

Central Standard Time (CST) covers Chicago and the surrounding region at UTC-6 / UTC-5 (CDT) from UTC. It observes Daylight Saving Time and shifts its clocks seasonally. Cities in this zone: Chicago, Dallas, Houston, Minneapolis, Kansas City, New Orleans, Winnipeg.

Yes. CST observes Daylight Saving Time and shifts its clocks by one hour in summer, while SGT stays fixed at UTC+8 year-round. The gap changes seasonally when CST transitions in or out of DST. The live converter auto-adjusts so you always see the right offset.

The best meeting window is where standard working hours (9 AM – 6 PM) overlap in both zones. Since CST is 14h behind of SGT, mornings in the earlier zone align with afternoons or evenings in the later zone. Target 8 AM – 11 AM in the earlier-offset zone to keep both sides in reasonable hours. The meeting hours table above shows the exact recommended slots for this pair. Any time where one side falls before 7 AM or after 9 PM is best avoided for regular team calls.

Type any time directly into the CST field in the bidirectional converter above — it instantly shows the SGT result. Alternatively, add 14 hours from the CST time manually. For a dedicated reverse page, visit: CST to SGT converter ↗.

Yes — this is a large offset, and many hours will cross midnight. When the converted time passes 11:59 PM, the date advances — the converter shows "+1 Day". When it goes before 12:00 AM, the date moves back — "-1 Day" appears. The 24-hour reference table also shows day changes in the Day column. Always check the date indicator when sending calendar invites across these two zones to avoid accidentally booking on the wrong date.

Singapore Standard Time (SGT) is used in: Singapore, Kuala Lumpur, Penang, Johor Bahru, George Town, Ipoh, Kuching. The zone operates at UTC+8, with a constant offset all year.

Central Standard Time (CST) covers: Chicago, Dallas, Houston, Minneapolis, Kansas City, New Orleans, Winnipeg. It runs at UTC-6 / UTC-5 (CDT)and observes Daylight Saving Time seasonally. Use the live clocks at the top of this page to see the current local time in both zones side by side.

The standard offset is 14h behind, but this can shift by one hour during DST transition periods. When CST moves to or from its daylight variant, the gap changes. The live converter always shows the current accurate offset.

When creating a recurring meeting that spans SGT and CST, set the event timezone in your calendar app using the IANA timezone names: Asia/Singapore for SGT and America/Chicago for CST. Using IANA names rather than fixed UTC offsets ensures the calendar app automatically adjusts future occurrences for any DST changes, so you never accidentally schedule at the wrong time after a clock transition. For a quick lookup of any specific time, the converter on this page is the fastest way to verify both sides before you send the invite.

No. Singapore has not observed Daylight Saving Time since 1982 and has maintained a fixed UTC+8 offset ever since. This makes SGT particularly easy to work with for recurring international meetings — the SGT side of any timezone pair is always exactly UTC+8, with no seasonal variation. SGT aligns numerically with Hong Kong Time (HKT), China Standard Time (CST8), Philippine Standard Time, and Australian Western Standard Time (AWST).
