There is no time difference between Lahore and Karachi. Both cities use Pakistan Standard Time (PKT, UTC+5). When it's 9:00 AM in Lahore, it's also 9:00 AM in Karachi.
Pakistan uses a single timezone across the entire country and does not observe daylight saving time.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 5:00 PM) without any time conversion needed.
Lahore and Karachi are Pakistan's two largest cities, connected by a 1.5-hour flight. Lahore is the cultural capital in the north, while Karachi is the commercial hub and largest port city in the south.
