What is the time difference between IST and PST?
PST is 13 hours 30 minutes behind IST. During March to November, when PST switches to PDT, the difference becomes 12 hours 30 minutes behind. 9:00 AM IST = 7:30 PM (previous day) PST. 12:00 PM IST = 10:30 PM (previous day) PST. 5:00 PM IST = 3:30 AM PST.
What is the best time to call from Mumbai to Los Angeles?
There is no 9-to-5 business hours overlap between IST and PST. The typical compromise is early morning IST: 8:00 AM IST (6:30 PM (previous day) PST), or late evening IST: 6:00 PM IST (4:30 AM PST). One side will be outside normal hours, so teams usually rotate who takes the off-hours call.
