Why Did the Time in the US Change?

Posted On: February 10, 2026

If your US meeting suddenly looks one hour earlier or later than usual, don’t worry—nothing went wrong. Many professionals working on India–US global teams ask, “Why did the time in the US change?”, especially in March and November when US clocks shift and India remains on IST.

The United States changes its clocks twice a year, while India stays on the same time year-round. This short 5-minute explainer video provides a quick, visual overview of the US time change and how it affects cross-border collaboration. Watching it first helps build clarity before diving into the details below.

Why the US Time Change Affects Global Teams

To understand why the time in the US changed, it helps to know that the US switches between Standard Time and Daylight Saving Time each year. India does not.

For India-based professionals collaborating with colleagues in New York, Chicago, Denver, or Los Angeles, this means meeting times shift by one hour—even when calendars and workflows stay the same.

For managers and HR or L&D leaders, this is less about clocks and more about cultural fluency: understanding how systems, norms, and expectations vary across regions.

Standard Time and Daylight Saving Time Explained

Standard Time

• • Used from November to March

  • Time zones end in ST (EST, CST, MST, PST)

Daylight Saving Time

• • Used from March to November

  • Clocks move one hour forward

  • Time zones end in DT (EDT, CDT, MDT, PDT)

India remains on IST year-round, reflecting a long-standing approach shaped by geography and national coordination—an example of how different systems evolve to meet local needs.

What Is EST vs EDT?

EST and EDT refer to the same US region, but at different times of the year.

• • EST → Eastern Standard Time (Nov–Mar)

  • EDT → Eastern Daylight Time (Mar–Nov)

When people ask why the US time change happened, they are often really asking which system—Standard or Daylight Saving—is currently in effect.

Frequently Asked Questions

Why did my meeting time suddenly change?

Nothing went wrong. The US changed its clocks, and India did not, so the time difference shifted by one hour.

What exactly changed?

The time difference between India and the US changed by one hour.

• • Before the change: US–India difference was 10.5 hours

  • After the change: US–India difference is 9.5 hours

(This depends on the US time zone your colleague is in.)

 

Is this a permanent change?

No. The change lasts several months and switches back in November.

When does the US change its clocks?

The US changes time twice a year:

• • March – clocks move forward (meetings feel earlier for India)

  • November – clocks move back (meetings feel later for India)

Exact dates vary slightly each year.

 

Does all of the US follow this time change?

Most states do, but Arizona (except Navajo Nation) and Hawaii do not observe Daylight Saving Time.

Does India have Daylight Saving Time?

No. India remains on IST throughout the year.

How can I avoid confusion when scheduling meetings?

Best practices:

• • Use a time-zone–aware calendar (Google Calendar, Outlook)

  • Schedule using your colleague’s time zone

  • Add the time zone label (e.g., “9:00 AM PT / 9:30 PM IST”)

  • Double-check meetings around March and November

Will this happen every year?

Yes, unless US laws change.
For now, expect this shift every March and November.

What’s the easiest way to check the correct time?

Use reliable tools like:

• • Google “9am Pacific time in India”

  • World Time Buddy

  • Timeanddate.com

These automatically adjust for Daylight Saving Time.

Why did the time in the US change but not in India?

Because the US observes Daylight Saving Time and India does not.

How can global teams reduce friction during time changes?

By naming time zones clearly, using shared scheduling tools, and building cultural fluency into collaboration practices.
