Open Meeting Planner →Calls between Singapore and Chicago usually connect banking and shipping on one side with finance and derivatives and logistics on the other. Put simply, when it is 09:00 in Chicago it is already 13 hours later in Singapore, on the following date.
The working week is Monday to Friday on both sides: roughly 09:00–18:00 in Singapore and 08:30–17:30 in Chicago. Watch for Chinese New Year (two days in January or February) and Hari Raya Puasa (end of Ramadan) in Singapore and Thanksgiving (fourth Thursday of November, with the Friday) and Independence Day (4 July) in Chicago.
The office days never overlap; the workable slots are Chicago's early morning against Singapore's evening. Rotate the inconvenience rather than fixing it on one side. Only Chicago changes its clocks, so the gap shifts by an hour twice a year while Singapore stays put.
Singapore is 13 hours ahead of Chicago. The gap changes by an hour around the clock changes.
There is no hour when both offices are open. The closest is early morning in Chicago against the end of the day in Singapore; alternate which side takes the awkward slot.
Alternate. A standing call that is always 07:00 for Chicago or always 19:00 for Singapore is resented within a month; rotating it keeps both sides in the room.
Not always. At 09:00 in Chicago it is already the next calendar day in Singapore, so every invitation should carry the date in both cities.
