Scheduling between UTC and IST
The working-day overlap is a few hours: morning in the zone that's behind matches afternoon in the zone that's ahead. For example, 9 AM UTC is 2:30 PM IST. Always write the city alongside the abbreviation in invites — several abbreviations (CST, IST, AST) are used by more than one region.
