About PST to EST conversion
Pacific Time and Eastern Time are the two edges of the continental United States, and the rule between them never changes: Eastern is three hours ahead of Pacific. When it is 9:00 AM in Los Angeles, San Francisco or Seattle, it is already noon in New York, Boston and Miami. Both coasts observe daylight saving on the same US dates (PDT is UTC-7, EDT is UTC-4), so the three-hour gap is identical in every season. This converter works from the real times in Los Angeles and New York, so the answer is right for any date you pick — including the clock-change weekends, when the gap holds but the abbreviations change.
Three hours is the difference that shapes US working life: the shared office window is only about five hours (9:00 AM–2:00 PM Pacific is 12:00–5:00 PM Eastern), a 4:00 PM Pacific deadline is a 7:00 PM Eastern one, and a prime-time show airing at 8:00 PM Eastern reaches Pacific screens at 5:00 PM. The day boundary matters too: anything from 9:00 PM Pacific onwards is already tomorrow in the East, and this page flags that instead of leaving you to spot it.

Frequently asked questions
The difference, daylight saving and the cases people trip over.
What is the time difference between PST and EST?
Three hours. Eastern Time is three hours ahead of Pacific Time — PST is UTC-8 and EST is UTC-5. The gap stays three hours during daylight saving (PDT UTC-7, EDT UTC-4) because both coasts change clocks on the same dates.
How do I convert PST to EST?
Add three hours. 8:00 AM PST is 11:00 AM EST, and 1:00 PM PST is 4:00 PM EST. Times from 9:00 PM PST onwards fall on the next calendar day in EST.
What is the best time for a call between the West and East Coasts?
The overlap of a 9-to-5 day on both coasts is 12:00 PM to 5:00 PM Eastern, which is 9:00 AM to 2:00 PM Pacific. A 10:00 AM Pacific start (1:00 PM Eastern) is the slot most cross-country teams settle on.
Does the PST to EST difference ever change?
Only for a few hours twice a year, in theory: both zones change clocks at 2:00 AM local time, so on transition nights the gap briefly differs while one coast has changed and the other has not. For any normal date and time, it is three hours — and this converter uses real city times, so even those nights are handled.
Which cities are in PST and EST?
Pacific includes Los Angeles, San Francisco, Seattle, Portland, San Diego and Las Vegas. Eastern includes New York, Boston, Washington DC, Atlanta, Miami and Toronto.
