Pennsylvania • Live Time-Zone Reference

Pennsylvania Time Zone

Pennsylvania uses Eastern Time (ET) statewide. Philadelphia, Pittsburgh, Harrisburg, Allentown, Erie, Reading, Scranton and all 67 Pennsylvania counties share the same official civil time. The Commonwealth uses EST at UTC−05:00 during standard time and EDT at UTC−04:00 during daylight saving time.

Quick answer: Pennsylvania has one time zone and no internal time-zone boundary. Use America/New_York for date-aware software calculations. Philadelphia and Pittsburgh—despite being on opposite sides of the Commonwealth—always share the same official clock under current rules.

Do Pennsylvania Borders Change the Clock?

No at ordinary land crossings under current rules. New York, New Jersey, Delaware, Maryland, West Virginia and Ohio all use Eastern Time along Pennsylvania's borders. That means a trip from Pennsylvania into any neighboring state does not create an immediate one-hour time-zone change.

Pennsylvania Standard Time vs Daylight Time

Pennsylvania currently observes the U.S. daylight-saving schedule statewide. In 2026 the Commonwealth advanced clocks on March 8 and is scheduled to return to standard time on November 1.

How Pennsylvania Time Works

Six facts explain nearly every Pennsylvania time-zone question, from statewide Eastern Time to the Philadelphia–Pittsburgh comparison, 67 counties, border travel and the current clock-change policy.

01 · Statewide

Pennsylvania Has One Time Zone

The entire Commonwealth uses Eastern Time. There is no Central, Mountain or Atlantic Time area inside Pennsylvania.

02 · Counties

All 67 Counties Share One Clock

Every Pennsylvania county follows the same EST/EDT schedule, from Philadelphia County in the southeast to Erie County in the northwest.

03 · East vs West

Philadelphia & Pittsburgh Match

Pennsylvania spans a large east–west distance, but Philadelphia and Pittsburgh always use the same official civil time.

04 · Borders

No Neighboring State Creates a Border Time Change

All six states bordering Pennsylvania use Eastern Time along their shared boundaries with the Commonwealth.

05 · IANA

Use America/New_York

America/New_York is the correct date-aware IANA zone for current and future Pennsylvania civil-time calculations.

06 · Policy

Pennsylvania Has Asked Congress to End Clock Changes

Senate Resolution 46 was adopted in 2025, but it was nonbinding and did not alter Pennsylvania's current EST/EDT schedule.

Does All of Pennsylvania Have the Same Time?

Yes. All 67 Pennsylvania counties use Eastern Time. Philadelphia and the Delaware Valley, Pittsburgh and Western Pennsylvania, Harrisburg and the Susquehanna Valley, Erie, the Poconos, the Lehigh Valley and every other region change between EST and EDT together.

This is especially useful for western Pennsylvania. Pittsburgh and Erie sit far west geographically, yet neither is in Central Time. Crossing the Ohio border also does not change the clock because Ohio is statewide Eastern Time.

67 countiesEvery Pennsylvania county follows the same official Eastern Time rules.
Philadelphia = PittsburghEastern and western Pennsylvania share the same clock throughout the year.
No in-state zone lineYou never change official time zones simply by traveling within Pennsylvania.

Is Pennsylvania Ending the Twice-Yearly Time Change?

No change is in force as of August 20, 2026. Pennsylvania continues to follow the current U.S. daylight-saving schedule, moving to EDT in March and returning to EST in November.

In the 2025–2026 General Assembly, Senate Resolution 46 petitioned Congress to end the biannual time change and establish a uniform, year-round time system. The Pennsylvania Senate adopted the resolution 47–2 on March 26, 2025, and it was transmitted as directed on April 8, 2025. The resolution did not itself alter Pennsylvania civil time, so the Commonwealth still observes seasonal EST/EDT transitions.

Visual Geography

Pennsylvania on the U.S. Time Zone Map

Pennsylvania sits entirely inside Eastern Time. No dedicated Pennsylvania state map is required for the current visual architecture, so Pennsylvania map queries are best served by the U.S. Time Zone Map, with the Eastern Time Zone Map providing the wider regional context.

Sources & Methodology

CalendarHours uses location-aware, date-aware time-zone logic rather than permanently hardcoding Pennsylvania as UTC−5 or UTC−4. America/New_York supplies the Eastern Time rules used throughout the Commonwealth.

The IANA Time Zone Database is the primary rules source for civil offsets and transitions. The latest release verified for this page is tzdb 2026c, released July 8, 2026. U.S. daylight-saving dates are checked against NIST. Pennsylvania's 67-county structure is checked against Commonwealth sources, and current time-policy activity is checked against official Pennsylvania General Assembly records.
