- Thursday, November 26, 2026 — Thanksgiving Day — Chicago is off, Singapore is working.
- Friday, December 25, 2026 — Christmas Day and Christmas Day; both cities are off.
Chicago and Singapore 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.
