when do clocks change in est
When DST ends, and standard time is observed between November and March, Indian teams working in EST business hours would come to the office between 7:30pm and 4:30am local time IST. I have calculated a 9 hour shift to allow for a one hour lunch break. The chart below provides information on the time change for the USA and Canada. The below chart provides information on spring ahead and fall back for Australia.
