PST to UTC Conversion Information

Time Zone Basics

Pacific Standard Time (PST) is observed in the western United States during winter months, including California, Washington, Oregon, and Nevada. Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time, serving as the global reference point.

Time Differences

Standard Time (PST): UTC is 8 hours ahead of PST. When it's 12:00 PM (noon) PST, it's 8:00 PM UTC.
Daylight Time (PDT): UTC is 7 hours ahead of PDT. When it's 12:00 PM (noon) PDT, it's 7:00 PM UTC.

• Pacific Time switches between PST (winter) and PDT (summer) due to daylight saving
• PST covers major cities like Los Angeles, San Francisco, Seattle, and Las Vegas
• Daylight saving time runs from the second Sunday in March to the first Sunday in November
• UTC is essential for international coordination, aviation, and computing systems

Why This Tool Exists

Coordinating across time zones shouldn’t take mental gymnastics. Pacific Time and UTC are frequently involved in scheduling tech meetings, international flights, and virtual events. This calculator is designed to do one thing well—help you convert time from PST or PDT to UTC without guessing or Googling. No fluff, no sign-up, no clutter.

How To Use It Step by Step

Set your local time

Pick a date and time in Pacific Time. The tool already detects if it’s in standard (PST) or daylight (PDT) mode depending on the date you choose. No need to worry about whether it's March or October—it figures it out for you.

Click “Convert PST to UTC”

Once you've entered your time, just hit the convert button. The tool instantly gives you the equivalent time in UTC. It also shows the day of the week and date, formatted clearly for quick reference.

Check the live clock

Right below the converter, the current time in both PST and UTC is displayed in real time. Handy if you're scheduling for right now or need to confirm how many hours ahead UTC is at this very moment.

Pick your format

Some folks like AM/PM. Others want 24-hour military style. Click the “12 Hour” or “24 Hour” button to switch formats. The setting updates the entire display and keeps your chosen format while you work.

What's Going On Behind the Scenes

This tool isn’t just doing a fixed calculation. It checks whether daylight saving time is active for your chosen date. From March 9 to November 2 in 2025, Pacific Time switches to daylight mode, which is only 7 hours behind UTC. Every other day of the year, it's 8 hours behind. The math adjusts automatically.

Questions That Come Up Often

What if I input a time during the transition?

If you enter a time that falls exactly at 2:00 AM during the DST change dates, the tool still processes it correctly. Whether it’s “spring forward” or “fall back,” you’ll get the right UTC time thanks to the built-in checks.

Why does the time zone label change?

The label above the input updates to reflect whether you’re in PST or PDT. That’s because the offset from UTC changes with daylight saving time. It keeps everything crystal clear.

Does this work both ways?

This version converts only from Pacific to UTC. If you’re trying to go in reverse, say, UTC to PST, use the same math, just subtract the offset. A future update may include reverse conversion.

One Real-World Scenario

Say you're organizing a webinar in Vancouver, Canada at 11:00 AM on April 15. Your audience includes researchers in Accra, Ghana. Input 11:00 AM PDT and hit convert, you’ll see it lands at 6:00 PM UTC. Everyone can plan around the same anchor point without miscommunication or timezone math.
