CST to SGT

About Central Time

Central Time covers the middle third of North America, from Manitoba down through Texas. It is UTC−6 as CST and UTC−5 as CDT, changing on the same dates as the other US zones — so the one-hour steps between Pacific, Mountain, Central and Eastern hold all year and never briefly collapse.

Cities on this clock: Chicago, Houston, San Antonio, Dallas, Austin, Nashville, Minneapolis, New Orleans.

Watch out: CST is also the abbreviation for China Standard Time, which is UTC+8 — fourteen hours away from this one. This page is the North American zone.

About Singapore Time

Singapore is a fixed UTC+8 even though it sits near 104°E, where solar noon falls closer to UTC+7 — it moved forward half an hour in 1982 to share a clock with peninsular Malaysia and Hong Kong. The practical effect is that the sun there rises and sets unusually late for the clock.

Cities on this clock: Beijing, Shanghai, Guangzhou, Shenzhen, Chongqing, Taipei, Hong Kong, Singapore.

How the difference is worked out

The gap between Central Time and Singapore Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 13 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.

With both zones on their own standard time — daylight saving not in force anywhere — Singapore Time is 14 hours ahead of Central Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.

Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids America/Chicago and Asia/Singapore. Nothing is looked up on a server and nothing about your visit is recorded.
