Time difference between Singapore and Chicago
Chicago is 13 hours behind Singapore
Singapore, Singapore is UTC+8 · Chicago, the United States is UTC−6 — on standard time
The gap is not the same all year
Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Singapore does not change its clocks and Chicago goes forward on the second Sunday in March and back on the first Sunday in November.
| Singapore / Chicago clocks | Difference | How long |
|---|---|---|
| standard / summer | 13 hours behind | about 34 weeks — most of the year |
| standard / standard | 14 hours behind | about 18 weeks |
Singapore stays put all year while Chicago moves, so the gap changes twice a year from Chicago's side alone. A recurring meeting set in Singapore's calendar will drift by an hour without anyone touching it.
When they can both be at their desks
Nine-to-five in Singapore and nine-to-five in Chicago do not overlap at all. With 13 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
