How many hours is PST behind EEST?
As abbreviations, EEST is always 11 hours ahead of PST: PST is UTC−8 and EEST is UTC+3. To convert, add 11 hours.
Check which label you actually need: PST (Pacific Time is on PDT today) and EEST (Eastern European Time is on EET today). A time written with an abbreviation that is not in use is usually meant as the local time, so convert between the places instead: right now EEST is 9 hours ahead of PST.
When the PST to EEST time difference changes
For most of the year EEST is 10 hours ahead of PST. From 25 October to 31 October 2026, EEST is 9 hours ahead of PST instead, because the two places change their clocks on different dates. Meetings booked by the usual gap land an hour off in those weeks.
