India–US Working Hours Overlap

Compare your actual India and US work schedules for a selected date. The result shows shared minutes—or explains why an agreed extension of one workday is needed.

Compare actual work windows

These are arithmetic comparisons of the selected hours, not confirmation of anyone’s workday. Check holidays, availability and whether extended hours are acceptable.

Why extended Indian hours are often needed

Chicago7:30 PM IST8:30 PM IST
Denver8:30 PM IST9:30 PM IST
Los Angeles9:30 PM IST10:30 PM IST

For example, an agreed 6–9 PM India window overlaps part of a New York morning. That is an extended-hours arrangement, not overlap between two ordinary 9–5 days. Phoenix and Honolulu follow different seasonal rules; select the actual city.

Agree on the extra hour before sending an invitation

In US daylight time, a New York 9 AM start is 6:30 PM IST. If the India team agrees to a 6–9 PM window and the New York team works 9 AM–5 PM, the common interval is 6:30–9 PM IST: 150 minutes. In US standard time, that same arrangement starts at 7:30 PM IST and has 90 shared minutes.

These are worked schedule assumptions. Put the participants’ actual daytime hours into the tool, read the dated result, and then create the invitation in a named city timezone. Overnight shifts need a separate planning method.

Turn a shared window into an invitation

Use the first shared instant from your chosen windows as a starting point, then choose the meeting length and confirm availability with both participants.
