Scheduling between the two

Working hours overlap from 9:00 am to 5:00 pm IST, which is 10:30 am to 6:30 pm ICT. 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

Indochina Time (ICT) is used in Thailand, Vietnam, Cambodia and Laos
