Why people convert Tehran to Russia time

Scheduling a call from Tehran to Russia: a 10:00 AM start in Tehran lands at 9:30 AM in Russia, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Tehran and Russia are inside the 9-to-5 working day between 9:30 AM and 5:00 PM IRST time (9:00 AM–4:30 PM MSK). That is roughly 7 hours 30 minutes of usable overlap.
Watching a live event or market open: Tehran viewers need 8:30 AM in Russia to catch a 9:00 AM start there, and 12:30 AM if the event is anchored to Tehran.

Always state the zone abbreviation, not just the hour. "3:00 PM IRST" is unambiguous; "3 PM" across a -0h 30m gap is not.
Block 9:30 AM–5:00 PM IRST as the recurring meeting window if you work primarily from Tehran and need Russia colleagues present.

About MSK (Moscow Standard Time)

Moscow Standard Time (MSK) is the time zone used in Moscow, St. Petersburg, and much of western Russia. Russia abolished DST in 2011, so MSK is observed year-round.
