When it's 8:00 AM Central Standard Time (CST) in the United States, the time in Singapore is 10:00 PM Singapore Standard Time (SST) on the same calendar day.
Calculation: Singapore (UTC+8) is 14 hours ahead of CST (UTC-6). During U.S. Daylight Saving Time (CDT, UTC-5), the difference narrows to 13 hours, making it 9:00 PM SST.
Singapore does not observe Daylight Saving Time, so the offset changes only when the U.S. switches between standard and daylight time.
