When the gap changes

Today Sydney is 16 hours ahead of Chicago.

  • November 1Chicago moves its clocks back and the gap becomes 17 hours.
  • March 14, 2027Chicago moves its clocks forward and the gap becomes 16 hours.
  • April 4, 2027Sydney moves its clocks back and the gap becomes 15 hours.
  • October 3, 2027Sydney moves its clocks forward and the gap becomes 16 hours.

The two are in opposite hemispheres, so one moves its clocks forward while the other moves them back, and the gap swings by two hours over the year.

Making it work

With no shared working hours, someone is always early or late. Rotate who that is: alternate the hour between Chicago's morning and Sydney's, so the same person is not on at 7 am every week.

Keep calls short and the rest written. Updates, reviews and anything that can wait a few hours do better as a message with a deadline than as a meeting that costs someone their evening.

When you do meet, offer two or three hours that each ask a little of both sides, and let the group vote. People accept an early start more readily when they chose it.
