For most of the year, working hours of 9:00 am to 6:00 pm in EDT correspond to 5:00 pm to 2:00 am (next day) in GST. At other times of the year, working hours of 9:00 am to 6:00 pm in EST correspond to 6:00 pm to 3:00 am (next day) in GST.For most of the year, working hours of 09:00 to 18:00 in EDT correspond to 17:00 to 02:00 (next day) in GST. At other times of the year, working hours of 09:00 to 18:00 in EST correspond to 18:00 to 03:00 (next day) in GST.
