11 AM PST → 8 PM in Helsinki (EET) / 9 PM (EEST)
Standard Time (Nov–Mar): PST = UTC-8, EET = UTC+2 → 10-hour difference.
11:00 AM PST + 10h = **9:00 PM EET** (Helsinki winter).
Daylight Saving (Mar–Oct): PDT = UTC-7, EEST = UTC+3 → 10-hour difference.
11:00 AM PDT + 10h = **9:00 PM EEST** (Helsinki summer).
| Period | PST/PDT | Helsinki | Diff | Result for 11 AM |
|---|
| Early Nov – mid Mar | PST (UTC-8) | EET (UTC+2) | +10h | 9:00 PM |
| Mid Mar – early Nov | PDT (UTC-7) | EEST (UTC+3) | +10h | 9:00 PM |
Why the Original Answer (8 PM) Was Off
It assumed a 9-hour gap (PST UTC-8 vs. EET UTC+1? or CET). Finland is **always UTC+2 (winter) / UTC+3 (summer)** — never UTC+1. The difference is **consistently 10 hours** year-round because both regions shift DST simultaneously (roughly).
