Why people convert SAST to Iran time

Scheduling a call from SAST to Iran: a 10:00 AM start in SAST lands at 11:30 AM in Iran, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both SAST and Iran are inside the 9-to-5 working day between 9:00 AM and 3:30 PM SAST time (10:30 AM–5:00 PM IRST). That is roughly 6 hours 30 minutes of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in SAST is 9:30 PM in Iran makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM SAST" is unambiguous; "3 PM" across a +1h 30m gap is not.
Block 9:00 AM–3:30 PM SAST as the recurring meeting window if you work primarily from SAST and need Iran colleagues present.
