Frequently asked questions

What is the time difference between Chicago and Sydney?

Chicago is 16 hours behind of Sydney: UTC-5 versus UTC+11. Both figures include any daylight saving currently in force.

What is the best time to call from Chicago to Sydney?

There is no hour that is comfortable for both. If the meeting is unavoidable, the least-bad options are the edges of each side's day — late morning in Chicago or early morning in Sydney — and the burden should be explicit rather than assumed.

Is there any way to make Chicago–Sydney meetings work?

Not through scheduling. With no overlap, the workable options are async written handoffs, recorded updates, or splitting coverage into two regional pods so that each pod works its own daylight hours.
