There is no time difference between Islamabad and Karachi. Both cities use Pakistan Standard Time (PKT, UTC+5). When it's 12:00 PM in Islamabad, it's also 12:00 PM in Karachi.
Pakistan uses a single timezone across the entire country, so all major cities remain synchronized.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 6:00 PM) without any time conversion needed.
Islamabad is Pakistan's capital and administrative center, while Karachi is the largest city and economic hub. Flights connect them in about 1.5 hours. Both are major business centers with strong connections.
