Why people convert Bucharest to Iran time

Scheduling a call from Bucharest to Iran: a 10:00 AM start in Bucharest lands at 10:30 AM in Iran, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Bucharest and Iran are inside the 9-to-5 working day between 9:00 AM and 4:30 PM EEST time (9:30 AM–5:00 PM IRST). That is roughly 7 hours 30 minutes of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in Bucharest is 8:30 PM in Iran makes it easy to avoid calling at 3 AM.
