Best time to schedule a call or meeting
Standard working hours in Bangkok and Chicago barely overlap, so a live call usually means one side joining early in the morning or late in the evening. The least disruptive option is to catch the very start or end of one city’s working day, or to handle things asynchronously.
A note on daylight saving
Chicago observes daylight saving but Bangkok does not, so the gap between them changes by an hour for part of the year. The 12 hours shown here is the current offset; expect it to shift around the daylight-saving changeovers (typically late March and late October in the Northern Hemisphere).
