Pacific Time vs. Eastern Time: What's the Difference?
Pacific Time (PT) is the time zone used on the West Coast of the USA, 3 hours behind Eastern Time (ET), the time zone used on the East Coast.
Pacific Time (PT) applies to the western part of the United States, including states like California and Washington, whereas Eastern Time (ET) is used in the eastern part, including states like New York and Florida.
PT is typically 3 hours behind ET, meaning when it's 12 PM in Pacific Time, it's 3 PM in Eastern Time. This time difference affects TV broadcasting schedules, business hours, and travel planning between these regions.
During daylight saving time, Pacific Time is referred to as Pacific Daylight Time (PDT) and is 2 hours behind Eastern Daylight Time (EDT). Outside daylight saving, it reverts to Pacific Standard Time (PST) and Eastern Standard Time (EST), maintaining the 3-hour difference.
PT's morning is ET's midday, impacting communication and coordination for businesses and individuals working across these zones. Conversely, evening in ET corresponds to late afternoon in PT, influencing prime time TV shows and live events' timings.
The time zone difference also plays a role in financial markets; when stock markets open at 9:30 AM in ET, it's 6:30 AM in PT, affecting trading strategies and business operations on both coasts.
