Why people convert Pakistan to IRST time

Scheduling a call from Pakistan to IRST: a 10:00 AM start in Pakistan lands at 8:30 AM in IRST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Pakistan and IRST 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 Pakistan-based team with IRST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM PKT" is unambiguous; "3 PM" across a -1h 30m gap is not.
Block 10:30 AM–5:00 PM PKT as the recurring meeting window if you work primarily from Pakistan and need IRST colleagues present.
