UTC to PST Time Converterv1.0.0

Converts dates and times between Coordinated Universal Time (UTC) and Pacific Standard Time (PST) using a fixed offset of UTC minus 8 hours. PST has no daylight saving adjustment, so the conversion does not switch to PDT (UTC minus 7). The result crosses calendar days when the offset moves past midnight, and the swap control reverses direction for PST to UTC.

The converter aligns a chosen date with a clock time, applies the fixed eight-hour offset between UTC and PST, and renders the result in the destination zone with weekday, full date, and clock value.

  1. Select the date that anchors the conversion. Use today when only the current offset matters.
  2. Choose 12-hour or 24-hour mode to match the format you want for both input and output.
  3. Enter the hour and minute. In 12-hour mode, set AM or PM.
  4. Click Calculate to run the conversion. The result appears in the Converted Time region with weekday, date, and time.
  5. Click Reset to clear all inputs, the output, and saved local-storage entries, then restore the default direction and mode.
  6. Click Swap Zones to flip between UTC to PST and PST to UTC. The input label, output label, and conversion table heading update accordingly.

The Real-Time Clock panel runs continuously and shows the current time in both UTC and PST so the offset is visible without converting a specific value. The Conversion Table below maps each whole UTC hour to its PST equivalent in both 12-hour and 24-hour formats. To verify any single hour, use the formula PST equals UTC minus 8, modulo 24. For the reverse direction, use UTC equals PST plus 8, modulo 24. When the result moves past midnight, the calendar day shifts forward or backward by one day. Saved inputs and the last selected direction and mode persist in local storage, so a return visit reopens with the same configuration.

Coordinating across time zones is a routine task for distributed teams, content publishers, support staff, and travelers. The UTC to PST converter reduces scheduling errors and gives a consistent reference point for both technical and everyday workflows. PST stays at UTC minus 8 year-round in this tool, so the offset never changes mid-calculation.

To convert from UTC to PST: PST = (UTC - 8) mod 24

To convert from PST to UTC: UTC = (PST + 8) mod 24

Plan a product demo at 18:30 UTC. Converting shows the demo occurs at 10:30 AM PST on the selected date. Schedule a release note for 7:00 PM PST. Swapping zones confirms that 19:00 PST maps to 03:00 UTC on the next calendar day. Review a log entry at 01:12 UTC and convert to verify it occurred at 5:12 PM PST on the previous day, which often matters for daily rollups and incident timelines. Share a calendar invite listed in UTC by converting to PST and placing the local time in the title to prevent confusion.

Time zone offsets shift the hour forward or backward, which can move the clock across midnight. When converting UTC to PST, subtracting eight hours can place the result on the previous day. When converting PST to UTC, adding eight hours can place the result on the next day.

Use the same process for any fixed-offset pair. Treat UTC as the source and substitute the target zone in place of PST. For a template, think in terms of {FROM_ZONE} to {TO_ZONE} with an offset of {OFFSET_HOURS}. Use the swap control to reverse direction.

Choose 12-hour mode to match common U.S. meeting invites. Choose 24-hour mode for technical workflows, scheduling scripts, or when you want to avoid AM and PM ambiguity.

No. The tool uses a fixed offset of UTC minus 8 hours for PST. It does not switch to PDT (UTC minus 7) during the months when Pacific Daylight Time would normally apply. For a result that follows daylight saving, add or subtract one hour manually during PDT months.
