CST currently runs on UTC−6 and IST on UTC+5:30, so CST is 11 hours 30 minutes behind IST. CST is currently on standard time, and IST does not observe daylight saving time. Because both cities follow their own clock rules, the 11 hours 30 minutes gap you see today can shift by an hour around the spring and autumn changeovers, which is why this page calculates every value live from the official time zone database instead of a fixed offset. There is no hour today when both offices are inside normal 09:00–18:00 hours, so one side will need to join early or late. Use the planner above to drag across a range, compare more cities, then copy a summary or add the slot straight to Google Calendar.
Daylight saving in CST and IST
CST follows North American rules: clocks go forward on the second Sunday in March and back on the first Sunday in November. IST keeps the same offset all year, so any change in the gap comes from the other location.
