Short answer: the US regular trading session runs from 16:30 to 23:00 Estonian time, Monday to Friday. Tallinn and New York both observe daylight saving time and switch within about a week of each other, so the gap stays at 7 hours nearly all year — the hours below apply in both summer (EEST) and winter (EET).
| Session | New York (ET) | Tallinn (EEST/EET) |
|---|---|---|
| Premarket | 04:00 – 09:30 | 11:30 – 16:30 |
| Regular session | 09:30 – 16:00 | 16:30 – 23:00 |
| After-hours | 16:00 – 20:00 | 23:00 – 03:00 |
| Weekend | Closed — Saturday and Sunday | |
The regular session is when the exchanges are fully open, most volume trades and the official closing prices are set. Premarket and after-hours have lower liquidity and wider spreads.
New York runs on Eastern Time (UTC−5 in winter, UTC−4 in summer). Tallinn runs on Eastern European Time (UTC+2 in winter, UTC+3 in summer). Because both switch clocks in spring and autumn, the offset is a steady 7 hours — except for a few days each March and November when the regions switch on different dates, which shifts the session by an hour for that week.
On some holidays the market closes early at 13:00 New York time (20:00 Tallinn) — typically the day after Thanksgiving and Christmas Eve.
16:30 in Tallinn. The opening bell in New York rings at 09:30 ET, which is 7 hours behind Estonia.
23:00 Tallinn time. After-hours trading then continues until roughly 03:00.
Yes — the US regular session falls entirely in the Estonian evening, which is one reason the hours matter to Baltic traders. Check quotes, sessions and volatility on IndexNexa's EEST-native terminal.
