Open Meeting Planner →Mumbai's finance and film and media and Chicago's finance and derivatives and logistics are different worlds, which is exactly why they call each other. Mumbai runs 10 hours 30 minutes ahead of Chicago, far enough that the morning in one is already the next day in the other.
The working week is Monday to Friday on both sides: roughly 09:30–18:30 in Mumbai and 08:30–17:30 in Chicago. Watch for Diwali (October or November) and Ganesh Chaturthi (August or September) in Mumbai 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 Mumbai'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 Mumbai stays put.
Mumbai is 10 hours 30 minutes 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 Mumbai; alternate which side takes the awkward slot.
Alternate. A standing call that is always 07:00 for Chicago or always 19:00 for Mumbai 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 Mumbai, so every invitation should carry the date in both cities.
