Why people convert Pakistan to Tehran time
- Scheduling a call from Pakistan to Tehran: a 10:00 AM start in Pakistan lands at 8:30 AM in Tehran, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Pakistan 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.
- Watching a live event or market open: Pakistan viewers need 7:30 AM in Tehran to catch a 9:00 AM start there, and 1:30 AM if the event is anchored to Pakistan.

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