Business hours commonly cluster around 08:00–16:00 or 09:00–17:00, varying by sector and season. The +03:30 quirk breaks whole-hour meeting math with Europe and the Gulf.
The +03:30 offset plus a moving DST policy is why “Iran time” must be Asia/Tehran, never a handmade UTC+3.5 cell. Recheck this page before a quarter-ahead board meeting.
