PST to EST Converter
Eastern Standard Time is 3 hours ahead of Pacific Standard Time. To convert PST to EST, add 3 hours. For example, 8:00 AM PST is 11:00 AM EST.
Eastern Standard Time is 3 hours ahead of Pacific Standard Time. To convert PST to EST, add 3 hours. For example, 8:00 AM PST is 11:00 AM EST.
Choose any Pacific Standard Time date and time. The primary result uses fixed PST (UTC−08:00) to fixed EST (UTC−05:00) and adds exactly three hours. A second line interprets the same wall-clock reading as date-aware Pacific Time in Los Angeles and converts that instant to Eastern Time in New York, exposing the brief 2-hour or 4-hour DST-transition gaps without changing the fixed PST→EST answer.
These common conversions use fixed Pacific Standard Time at UTC−08:00 and fixed Eastern Standard Time at UTC−05:00. PST times from 9:00 PM onward cross midnight and land on the next EST calendar day.
8:00 AM PST = 11:00 AM EST. Same calendar day.
See in table →12:00 PM PST = 3:00 PM EST. Same calendar day.
See in table →3:00 PM PST = 6:00 PM EST. Same calendar day.
See in table →5:00 PM PST = 8:00 PM EST. Same calendar day.
See in table →9:00 PM PST = 12:00 AM EST on the next calendar day.
See date rollover →Add exactly three hours because PST is UTC−08:00 and EST is UTC−05:00.
Learn the rule →Use this complete reference for every whole hour of the day. The fixed difference is always three hours; the date column flags evening PST times that land on the next EST calendar day.

PST→EST is always a three-hour conversion: UTC−08:00 to UTC−05:00. Real Pacific and Eastern clocks are date-aware. Los Angeles can use PDT (UTC−07:00) and New York can use EDT (UTC−04:00). Most of the year those cities are also three hours apart. In 2026, New York changes first on March 8, producing a four-hour gap from 07:00 through 09:59 UTC; on November 1 it changes back first, producing a two-hour gap from 06:00 through 08:59 UTC. The fixed PST→EST difference remains three hours throughout.
The exact fixed conversion is simple: EST = PST + 3 hours. Start with the PST time, add three hours, and move to the next calendar day if the result passes midnight.
Adding three hours changes the EST calendar date for PST times between 9:00 PM and 11:59 PM. At 8:59 PM PST the EST result is still on the same calendar date; at 9:00 PM PST it becomes 12:00 AM EST on the next day.
With conventional 9:00 AM–5:00 PM workdays in both fixed zones, the shared business-hours window is 9:00 AM–2:00 PM PST, which is 12:00 PM–5:00 PM EST.
Converts to 12:00–17:00 EST and keeps both sides inside a conventional workday.
A strong default: the Pacific day is starting while the Eastern side is at noon.
A comfortable midday Pacific slot that remains within Eastern business hours.
PST is the fixed standard-time offset UTC−08:00. It is not interchangeable with PDT (UTC−07:00) or the broader term Pacific Time, which can be date-dependent.
EST is the fixed standard-time offset UTC−05:00. It is not interchangeable with EDT (UTC−04:00) or the broader term Eastern Time, which can be date-dependent.
Use these exact directional converters when you need the reverse direction, another U.S. standard-time pair, or a UTC reference for one side of the conversion.
Four details prevent most PST-to-EST mistakes: both abbreviations are fixed offsets, the fixed difference is always three hours, late-evening PST can land on the next EST date, and real Pacific/Eastern locations can briefly have a 2-hour or 4-hour gap around U.S. DST transitions.
The fixed PST→EST conversion is arithmetic: PST is UTC−08:00 and EST is UTC−05:00, so EST is always three hours later. For real-location comparisons, CalendarHours uses date-aware IANA time-zone identifiers for Los Angeles and New York so PDT, EDT and U.S. daylight-saving transitions can be reflected for the selected date.

A converter labeled “PST to EST” should preserve the mathematical meaning of the abbreviations: UTC−08:00 to UTC−05:00, always a three-hour difference. Real Pacific and Eastern Time locations usually remain three hours apart too, but their DST changes occur at 2:00 AM local time, which means the transitions happen three UTC hours apart. During those brief transition windows, Los Angeles and New York can be four hours apart in spring or two hours apart in fall.
Quick answers to the most common Pacific Standard Time to Eastern Standard Time conversion questions.
Add 3 hours to PST. Pacific Standard Time is UTC−08:00 and Eastern Standard Time is UTC−05:00, so 8:00 AM PST is 11:00 AM EST.
Yes, when PST and EST mean the exact fixed standard-time abbreviations. PST is UTC−08:00 and EST is UTC−05:00, so EST is always exactly 3 hours ahead of PST.
Not exactly. PST is the fixed UTC−08:00 standard-time phase. Pacific Time (PT) can use PST or Pacific Daylight Time (PDT, UTC−07:00), depending on the date and location.
Not exactly. EST is the fixed UTC−05:00 standard-time phase. Eastern Time (ET) can use EST or Eastern Daylight Time (EDT, UTC−04:00), depending on the date and location.
8:00 AM PST is 11:00 AM EST on the same calendar day.
12:00 PM PST is 3:00 PM EST on the same calendar day.
3:00 PM PST is 6:00 PM EST on the same calendar day.
5:00 PM PST is 8:00 PM EST on the same calendar day.
PST times from 9:00 PM through 11:59 PM convert to the next calendar day in EST because adding three hours crosses midnight.
Yes, briefly around U.S. daylight-saving transitions. In 2026, New York is 4 hours ahead of Los Angeles from 07:00 through 09:59 UTC on March 8, and 2 hours ahead from 06:00 through 08:59 UTC on November 1. Fixed PST and fixed EST themselves remain exactly 3 hours apart.
For conventional 9:00 AM to 5:00 PM workdays in both fixed zones, the shared window is 9:00 AM to 2:00 PM PST, which is 12:00 PM to 5:00 PM EST.
