Why people convert Karachi to EST time

Scheduling a call from Karachi to EST: a 10:00 AM start in Karachi lands at 12:00 AM in EST, so you can confirm the slot without doing the arithmetic yourself.
Handling a -10h gap: Karachi and EST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in EST is 11:00 PM in Karachi.
Booking travel or deliveries: tracking EST local time against Karachi keeps pickup windows and arrival estimates honest across the -10h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM PKT" is unambiguous; "3 PM" across a -10h gap is not.
With a -10h gap there is no shared 9-to-5 window, so alternate the early start: one week Karachi takes the early slot, the next week EST does.
