Figuring out the time difference between the United States and Pakistan can feel like solving a puzzle, especially because the US spans multiple time zones and observes daylight saving time while Pakistan does not. Whether you're planning a business call with a team in Islamabad, scheduling a family video chat, or coordinating international logistics, getting the exact math right is essential to avoid missed appointments.
The time difference between the US and Pakistan ranges from 8 to 13 hours, depending entirely on which US time zone you are calling from and whether daylight saving time is currently in effect. Pakistan standard time sits firmly at UTC+5 year-round, meaning it never shifts its clocks forward or backward. Because most of the US observes daylight saving time from March to November, the gap between the two countries fluctuates by an hour twice a year.
Understanding Pakistan Time Zone Basics
Pakistan operates on a single national time zone known as Pakistan Standard Time, abbreviated as PKT. This zone is consistently five hours ahead of Coordinated Universal Time, written as UTC+5.
Unlike the United States, which is broken up into several distinct geographical zones, Pakistan spans a single time zone from its bustling southern ports in Karachi up to the northern mountain passes near the Chinese border. Furthermore, the country abolished daylight saving time trials several years ago. This consistency makes calculating time against PKT straightforward once you determine your own local US offset.
To visualize how PKT fits into the global clock, consider these baseline offsets from UTC:
- Eastern Standard Time: UTC-5
- Central Standard Time: UTC-6
- Mountain Standard Time: UTC-7
- Pacific Standard Time: UTC-8
- Pakistan Standard Time: UTC+5
US Time Zones and Daylight Saving Time Impact
The United States uses multiple standard time zones across the mainland and its territories. During standard time—which runs roughly from early November to mid-March—the gap between the US and Pakistan is at its widest. When daylight saving time begins in the second week of March and lasts until the first Sunday of November, US clocks spring forward one hour, which narrows the gap by an hour.
Let's break down the exact time differences for each major US continental time zone during both seasonal periods.
Eastern Time Zone (ET)
The Eastern time zone includes major hubs like New York, Washington D.C., Atlanta, and Miami.
During standard time, Eastern Standard Time (EST) is UTC-5. Since Pakistan is UTC+5, the time difference is exactly 10 hours. Pakistan is 10 hours ahead of the US East Coast. For example, when it is 9:00 AM on a Tuesday in New York, it is 7:00 PM on the same Tuesday in Karachi.
During daylight saving time, Eastern Daylight Time (EDT) shifts to UTC-4. Because Pakistan stays at UTC+5, the gap shrinks to 9 hours. When it is 9:00 AM EDT in New York, it is 6:00 PM PKT in Pakistan.
Central Time Zone (CT)
Covering cities like Chicago, Dallas, Houston, and St. Louis, the Central time zone sits one hour behind the East Coast.
In the winter months during Central Standard Time (CST, UTC-6), Pakistan is 11 hours ahead. When it is 8:00 AM CST in Chicago, it is 7:00 PM PKT in Pakistan.
In the summer months during Central Daylight Time (CDT, UTC-5), Pakistan is 10 hours ahead. When it is 8:00 AM CDT in Chicago, it is 6:00 PM PKT in Pakistan.
Mountain Time Zone (MT)
Spanning states like Colorado, Utah, Arizona (mostly without daylight saving), and parts of Idaho and Montana, Mountain time adds another hour of distance.
During Mountain Standard Time (MST, UTC-7), Pakistan is 12 hours ahead. A morning meeting at 7:00 AM MST in Denver corresponds to 7:00 PM PKT in Pakistan.
During Mountain Daylight Time (MDT, UTC-6), Pakistan is 11 hours ahead. A 7:00 AM MDT check-in equals 6:00 PM PKT.
Pacific Time Zone (PT)
The Pacific time zone covers West Coast powerhouses like Los Angeles, San Francisco, Seattle, and Las Vegas.
During Pacific Standard Time (PST, UTC-8), Pakistan is 13 hours ahead. This represents the maximum gap between the continental US and Pakistan. When you wake up at 6:00 AM PST in Los Angeles, your colleagues in Lahore are already finishing their workday at 7:00 PM PKT.
During Pacific Daylight Time (PDT, UTC-7), the gap drops to 12 hours. A 6:00 AM PDT start in Seattle lands right at 6:00 PM PKT in Pakistan.
Quick Reference Conversion Table
To make scheduling fast and frictionless, use this overview of standard and daylight periods.
- US Eastern Zone: 10 hours ahead (Winter) / 9 hours ahead (Summer)
- US Central Zone: 11 hours ahead (Winter) / 10 hours ahead (Summer)
- US Mountain Zone: 12 hours ahead (Winter) / 11 hours ahead (Summer)
- US Pacific Zone: 13 hours ahead (Winter) / 12 hours ahead (Summer)

Scheduling International Calls and Meetings
Finding a convenient overlap for a meeting across a 9- to 13-hour gap requires careful planning. A standard 9:00 AM to 5:00 PM workday in the United States barely intersects with traditional working hours in Pakistan.
If you are on the US East Coast during daylight saving time (a 9-hour difference), a morning in New York works best for late afternoon in Pakistan:
- 9:00 AM EDT in New York equals 6:00 PM PKT in Pakistan.
- 11:00 AM EDT in New York equals 8:00 PM PKT in Pakistan.
- 1:00 PM EDT in New York equals 10:00 PM PKT in Pakistan.
If you are on the US West Coast during standard time (a 13-hour difference), early morning US calls hit late evening Pakistani time:
- 7:00 AM PST in Los Angeles equals 8:00 PM PKT in Pakistan.
- 8:00 AM PST in Los Angeles equals 9:00 PM PKT in Pakistan.
For remote teams, tools like TimeAndDate help visualize overlapping windows before sending calendar invites.
Common Mistakes to Avoid
Managing time zone conversions between distant regions often leads to predictable errors. Keeping these pitfalls in mind will save you from missed calls.
- Forgetting Daylight Saving Transition Dates: The US shifts its clocks on the second Sunday of March and the first Sunday of November. Pakistan does not change its clocks. There is always a brief mismatch period where international meetings scheduled automatically by calendar apps might drift by an hour if the system isn't updated.
- Assuming Arizona and Hawaii Follow the Same Rules: Arizona (except for the Navajo Nation) and Hawaii do not observe daylight saving time. If you coordinate with someone in Phoenix during the summer, they stay on Mountain Standard Time (UTC-7), making the math different from states observing MDT.
- Confusing AM and PM Across Date Lines: Because Pakistan is up to 13 hours ahead, a Monday morning in California is already Monday evening in Pakistan. If you schedule something for late Monday night in the US, it is already Tuesday morning in Pakistan. Always check the calendar date for both participants.
Frequently Asked Questions
Does Pakistan observe daylight saving time?
No, Pakistan does not currently observe daylight saving time. The country tested daylight saving measures in the past but abandoned the practice due to minimal energy savings and public confusion. Pakistan Standard Time remains at UTC+5 year-round.
Why is the time difference between the US and Pakistan so large?
Pakistan sits in Central Asia, while the continental United States spans North America. This geographic separation covers multiple longitudinal degrees, creating a natural gap of roughly 8 to 13 hours depending on your exact US starting point.
How do I handle daylight saving time changes on calendar apps?
Most modern digital calendars like Google Calendar or Outlook handle time zone conversions automatically when you input the correct location and time zone. However, always double-check event times during the transition weeks in March and November to ensure your software has adjusted for the one-hour shift.
What is the best time of day for a phone call between New York and Islamabad?
The most practical window for a live conversation is early morning in New York (between 8:00 AM and 10:00 AM EDT), which falls during the late afternoon and early evening in Pakistan (between 5:00 PM and 7:00 PM PKT). This allows both parties to connect within standard working hours.
