Scheduling between the two

Working hours overlap from 12:00 pm to 6:00 pm IST, which is 9:30 am to 3:30 pm TRT. Anything inside that window falls in the normal working day at both ends.

A note on IST: it can also mean Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1). This page means India Standard Time, which is what almost all searches for IST want.

India Standard Time (IST) is used in all of India and Sri Lanka, on a single UTC+5:30 offset with no daylight saving

Turkey Time (TRT) is used in all of Türkiye, on a permanent UTC+3 since 2016
