Best Time to Call USA (+1): Global Time Zone Guide

"One ring at the wrong hour = one missed deal, friend, or moment."

Calling someone in the USA sounds simple, until you realize they’re asleep when you ring, or you’ve accidentally called during their lunch break.

Whether it’s for business, family, or something urgent, getting the timing right makes a big difference. Nobody wants to deal with missed calls or “Why are you calling me now?” moments.

The thing is, the USA doesn’t have just one time, it runs across several time zones. So depending on where you are, and where your call’s going (overseas), you might be hours off without even realizing it.

That’s where this guide comes in.

I’ve put together a clear and simple breakdown of how USA time zones work, how to figure them out easily, and the best time to call USA from different countries, so you can avoid those awkward “oops, wrong time” moments for good…

USA Time Zones Explained

So, how many time zones does the USA actually have?

Short answer: six.

Most people think there are only four time zones in the USA. But in reality, there are six.

The main four are Eastern, Central, Mountain, and Pacific Time, the ones most of the mainland follows. The remaining two are Alaska Standard Time and Hawaii-Aleutian Standard Time, used only in Alaska and Hawaii.

And we’re not talking about small shifts. The time difference from one coast to the other can stretch up to six full hours. That’s a big deal if you're calling from another country, you don’t want to ring someone at the wrong time.

Let’s say it’s 12:00 PM (noon) UTC, the universal reference time.

Here’s what that means across different parts of the USA:

• In New York (EST) it would be 7:00 AM
• In Chicago (CST) it would be 6:00 AM
• In Denver (MST) it would be 5:00 AM
• In Los Angeles (PST) it would be 4:00 AM
• In Alaska (AKST) it would be 3:00 AM
• And in Hawaii (HAST) it would be 2:00 AM

So, one country, six clocks. That’s why knowing the time zone is a must before making your call.

Here’s the simple breakdown:

UTC means Coordinated Universal Time.

Every country compares its local time to UTC, kind of like the world’s central clock.

Phoenix doesn’t follow Daylight Saving Time, so it usually stays on MST all year.

• EST = Eastern Standard Time (used in winter),
• EDT = Eastern Daylight Time (used in summer)

(Same format applies to all zones with DST)

Best Time to Call USA from Different Countries

The best time to call USA really depends on where you're calling from. Because the US has six time zones, even a few hours can make a big difference. A perfect evening for you might be the middle of the night for someone in the States.

To help you avoid awkward timing, missed calls, or half-asleep “hello?” moments, I’ve broken it down by country. That way, you’ll know exactly when to call, no matter where you are in the world.

From India to USA

If you’re in India, calling someone in USA means dealing with a major time gap. India is ahead of the USA by 9.5 to 15.5 hours, depending on the American time zone. So, while it's your evening, it might still be early morning, or even the middle of the night, in the States.

Here’s a simple breakdown:

So, if you call during the best times listed, the time in the U.S. will usually be between 8:00 AM and 12:00 PM.

The best time to call USA from India is between 6:30 PM and 10:30 PM IST.

This matches with morning time in the U.S. (around 8 AM to 12 PM), when people are just starting their day. They’re more likely to pick up the phone, check messages, and talk. It’s a good time for both business and personal calls, and you won’t be waking anyone up.

From the United Kingdom to USA

Calling USA from UK is easier to manage compared to some other countries, but you still need to time it right. The UK is ahead of the USA by 5 to 10 hours, depending on the American time zone.

This means when it’s your afternoon, most of the U.S. is just starting their workday, and that’s your best time.

Here’s a simple breakdown:

From Canada to USA

If you’re in Canada, calling USA is pretty easy. Most parts of Canada share the same time zones as the U.S, or are just 1–2 hours apart. That means you don’t have to worry too much about waking someone up or calling at odd hours.

Still, the best time to call depends on which U.S. time zone you're trying to reach. Most of Canada follows Eastern, Central, or Pacific time, just like the U.S. So, a morning or early afternoon call usually works best.

Here’s a simple breakdown:

The best time to call USA from Canada is between 9:00 AM and 1:00 PM in your local Canadian time zone. This lines up with morning in the U.S, which is ideal for getting responses, making meetings, or just having a relaxed conversation.

From Australia to USA

Calling the USA from Australia takes a little more planning. There’s a huge time gap, the U.S. is usually 12 to 19 hours behind, depending on both your city and where you're calling in the U.S.

And just like the U.S., Australia runs on three main time zones, each with a slightly different time difference:

• AEST (Australian Eastern Standard Time) – 14 to 19 hours ahead of U.S. time zones
• ACST (Australian Central Standard Time) – 14.5 to 19.5 hours ahead of U.S. time zones
• AWST (Australian Western Standard Time) – 16 to 21 hours ahead of U.S. time zones

Because of this, your early morning (or very late night) is usually the prime time to reach someone in the U.S. during their morning or mid-day, when they’re most likely to pick up and respond.

Here’s a simple breakdown:

Worth a Look: Best Time to Australia

Time Zone Reference Used:

The "Best Time to Call" column is calculated using AEST (UTC+10).

From there, I adjusted the ACST and AWST timings manually:

• ACST (UTC+9:30) = AEST minus 30 minutes
• AWST (UTC+8) = AEST minus 2 hours

If you're calling from Australia during the recommended late-night or early-morning hours, it’ll be daytime in the U.S, usually between 9:00 AM and 1:00 PM. That’s prime time when Americans are active, checking messages, and ready to talk.

Best time to call USA from Australia is 6:00 AM to 9:00 AM (AEST), 5:30 AM to 8:30 AM (ACST), and 4:00 AM to 7:00 AM (AWST), this lands in the U.S. morning hours (8:00 AM to 11:00 AM), when people are starting their day and more likely to answer.
