Chicago to Singapore time
Singapore is 13 hours ahead of Chicago. Chicago uses America/Chicago (UTC−5); Singapore uses Asia/Singapore (UTC+8).
When the time difference changes
The two places don't switch daylight saving time on the same days, so the gap shifts during the year:
- Sun, Nov 1, 2026: Chicago falls back an hour. Then Singapore is 14 hours ahead of Chicago.
- Sun, Mar 14, 2027: Chicago springs forward an hour. Then Singapore is 13 hours ahead of Chicago.
Best times to meet
Working hours (9 AM to 5 PM) don't overlap today. The best compromise times are below.
- 1 8:00 PM in Chicago = 9:00 AM (Tue) in Singapore
- 2 6:00 PM in Chicago = 7:00 AM (Tue) in Singapore
- 3 7:00 PM in Chicago = 8:00 AM (Tue) in Singapore
Jet lag and travel: Chicago to Singapore
Your body clock shifts 11 hours later (westward, the easier direction), the shorter way round a 13-hour gap. Expect about 8 days to adjust at CDC average rates (1 h/day east, 1.5 h/day west).
- Before you fly: bed 1 hour later for 2–3 nights.
- On arrival: eat, sleep and get daylight on Singapore time.
- Trips of 2 days or less: consider staying on Chicago time.
