Chicago uses Central Time — Central Standard Time (CST, UTC−6) in winter and Central Daylight Time (CDT, UTC−5) in summer, shifting on the same US DST schedule. It sits one hour behind Eastern Time and two hours ahead of Pacific, placing it in the heart of US business scheduling overlap.
Singapore uses Singapore Time (SGT, UTC+8) year-round with no Daylight Saving Time. Singapore is situated near the equator, which means daylight hours barely vary throughout the year, making DST unnecessary. SGT aligns with Kuala Lumpur (MYT), Hong Kong (HKT), and China (CST).
Both Chicago and Singapore may observe Daylight Saving Time, which means the offset between them can change twice a year. Here is what to expect each season.
| Period | Note | Chicago | Singapore | Offset |
|---|---|---|---|---|
| Nov – Mar | Both on standard time | CST (UTC−6) | GMT+8 (UTC+8) | 14 hours |
| Mar – late Mar | US clocks forward, some zones still on standard | CDT (UTC−5) | GMT+8 (UTC+8) | 13 hours |
| Late Mar – Oct current | Both on summer / daylight time | CDT (UTC−5) | GMT+8 (UTC+8) | 13 hours |
| Late Oct – early Nov | Clocks transitioning — check exact date | CST (UTC−6) | GMT+8 (UTC+8) | 14 hours |
The transition window typically lasts 1–2 weeks in spring and autumn. If you have a recurring weekly meeting near a clock change, verify the exact date to avoid a missed call.
