When the gap changes in the next twelve months

Sunday, March 14, 2027 — Mumbai goes from 11 hours 30 minutes ahead of to 10 hours 30 minutes ahead of Chicago.

Recurring meetings set as a fixed clock time in one city will move by an hour for the other on that date.

Public holidays to avoid

Dates where one side is off work while the other is not are the most common cause of no-shows on this route.

Wednesday, November 11, 2026 — Veterans Day — Chicago is off, Mumbai is working.
Thursday, November 26, 2026 — Thanksgiving Day — Chicago is off, Mumbai is working.
Friday, December 25, 2026 — Christmas Day — Chicago is off, Mumbai is working.

Chicago and Mumbai have no shared working hours, so a recurring live meeting always costs someone their morning or their evening. Rotating the burden, or moving the update to written form, is usually the better answer.

Sending a booking link avoids the arithmetic entirely: each side picks a time in their own zone and both calendars get the correct local time, including after a daylight-saving change. See how LemCall handles cross-timezone bookings.
