Time difference between Indianapolis and Sydney

Does the gap change?

The gap isn't fixed. Indianapolis and Sydney both use daylight saving time, but they change their clocks on different dates and in opposite seasons, so the difference moves during the year:

• From around November 2, 2026: Sydney ahead by 16 hours
• From around March 15, 2027: Sydney ahead by 15 hours
• From around April 4, 2027: Sydney ahead by 14 hours
• From around October 3, 2027: Sydney ahead by 15 hours

Best time to meet

Normal office hours in Sydney and Indianapolis don't overlap. The most workable window is 4 PM to 10 PM in Indianapolis, which is 7 AM to 1 PM in Sydney, with one side starting early or finishing late.

For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
