Why people convert PKT to Tehran time
- Scheduling a call from PKT to Tehran: a 10:00 AM start in PKT lands at 8:30 AM in Tehran, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both PKT and Tehran are inside the 9-to-5 working day between 10:30 AM and 5:00 PM PKT time (9:00 AM–3:30 PM IRST). That is roughly 6 hours 30 minutes of usable overlap.
- Coordinating a PKT-based team with Tehran contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

- Block 10:30 AM–5:00 PM PKT as the recurring meeting window if you work primarily from PKT and need Tehran colleagues present.
