UTC to PT Converter

Pacific Time is 7 or 8 hours behind UTC depending on the date. PT uses Pacific Daylight Time (PDT, UTC−07:00) during daylight saving time and Pacific Standard Time (PST, UTC−08:00) during standard time for the U.S. Pacific schedule.

UTC to PT is date-aware. For example, 3:00 PM UTC is 8:00 AM PT during PDT or 7:00 AM PT during PST. Choose a date below and the converter automatically uses the Pacific offset in effect for that instant using America/Los_Angeles as the reference.

Pacific Time Is a Date-Aware Clock

PT is the umbrella term. Pacific Daylight Time (PDT) is UTC−07:00, while Pacific Standard Time (PST) is UTC−08:00. A correct UTC→PT conversion therefore needs the date, not just the clock time. For a fixed offset, use the dedicated UTC→PDT or UTC→PST converter.

How to Convert UTC to PT

UTC to Pacific Time is a two-rule conversion because the U.S. Pacific offset changes with daylight saving time. The date-aware converter handles the phase automatically.

1. Start with the UTC date and timeThe date matters because PT can be on PDT or PST.
2. Determine the Pacific phasePDT uses UTC−07:00; PST uses UTC−08:00.
3. Subtract 7 or 8 hoursExample: 15:00 UTC becomes 08:00 PDT or 07:00 PST.
4. Check the Pacific calendar dateEarly UTC hours can land on the previous day in Pacific Time.

Best Time for a UTC to PT Meeting

For conventional 9:00 AM–5:00 PM workdays, there is one full hour of overlap during PDT: 4:00 PM–5:00 PM UTC equals 9:00 AM–10:00 AM PT. During PST there is no full one-hour overlap; 5:00 PM UTC equals 9:00 AM PT, exactly as the UTC workday ends.

During PDT

16:00–17:00 UTC

Converts to 09:00–10:00 PT and gives one full hour inside conventional workdays in both zones.

During PST

17:00 UTC = 09:00 PT

The Pacific workday begins exactly when a conventional UTC 9-to-5 workday ends, so there is no full one-hour overlap.

Practical compromise

16:30–17:30 UTC

Spans 09:30–10:30 PDT or 08:30–09:30 PST; useful when one side can flex slightly beyond a strict 9-to-5 window.

UTC

Coordinated Universal Time

UTC is the global time standard used as the reference for civil time zones and UTC offsets. It does not move forward or backward for daylight saving time.

Pacific Time

Pacific Time is a regional clock system rather than one fixed UTC offset. Under the U.S. Pacific schedule it alternates between PDT at UTC−07:00 and PST at UTC−08:00, so conversions should be date-aware.

UTC to PT: Precision Notes

Four details prevent most Pacific Time mistakes: PT is date-aware, PDT and PST use different offsets, the transition date matters, and Pacific-time rules can differ by jurisdiction.

Sources & Methodology

UTC is treated as UTC+00:00. Pacific Time on this page is calculated with the IANA zone America/Los_Angeles, allowing the browser to apply the correct U.S. Pacific civil-time rule and return PST or PDT for the selected instant instead of hardcoding one offset year-round.

IANA Time Zone Database — civil-time rules and current tzdb releases NIST — U.S. daylight saving time rules

Last reviewed: August 22, 2026. Live values are calculated in the browser with date-aware time-zone data available to the user's system.

Why UTC to PT Needs a Date

Unlike UTC→PST or UTC→PDT, UTC→PT does not have one permanent subtraction rule. Under the U.S. Pacific schedule, Pacific Time can be UTC−07:00 or UTC−08:00. Using a real IANA zone for the chosen instant prevents a one-hour error around daylight-saving periods.

UTC to PT FAQ

Quick answers to the most common UTC-to-Pacific-Time conversion questions.

How do you convert UTC to PT?

Use the date to determine whether Pacific Time is observing PDT (UTC−07:00) or PST (UTC−08:00), then subtract 7 or 8 hours from UTC. This converter applies the correct Pacific offset automatically for the selected date.

Is Pacific Time 7 or 8 hours behind UTC?

Pacific Time can be either 7 or 8 hours behind UTC. It is UTC−07:00 while Pacific Daylight Time (PDT) is in effect and UTC−08:00 while Pacific Standard Time (PST) is in effect.

Is PT the same as PST?

No. PT means Pacific Time, the regional clock system that can use PDT or PST depending on the date. PST is specifically the UTC−08:00 standard-time phase.

Is PT the same as PDT?

No. PDT is the UTC−07:00 daylight-time phase of Pacific Time. PT can mean PDT during daylight saving time or PST during standard time for locations that follow the U.S. Pacific schedule.

What is 8 AM UTC in Pacific Time?

8:00 AM UTC is 1:00 AM PT when PDT is active or 12:00 AM PT when PST is active. Use the date-aware converter for the exact result.

What is 12 PM UTC in Pacific Time?

12:00 PM UTC is 5:00 AM PT during PDT or 4:00 AM PT during PST.

What is 3 PM UTC in Pacific Time?

3:00 PM UTC is 8:00 AM PT during PDT or 7:00 AM PT during PST.

What is 5 PM UTC in Pacific Time?

5:00 PM UTC is 10:00 AM PT during PDT or 9:00 AM PT during PST.

When does UTC to PT change the calendar date?

During PDT, UTC times from 12:00 AM through 6:59 AM convert to the previous Pacific calendar day. During PST, UTC times from 12:00 AM through 7:59 AM convert to the previous Pacific calendar day.

What is the best time for a UTC to PT meeting?

During PDT, 4:00 PM to 5:00 PM UTC corresponds to 9:00 AM to 10:00 AM Pacific Time, giving one full hour inside conventional 9-to-5 workdays in both zones. During PST there is no full one-hour overlap because 5:00 PM UTC is 9:00 AM PT.
