US market holidays and half days

Which days the New York exchanges are closed, which days they close early — and what that means in Istanbul time. Turkey has not changed its clocks since 2016, so the gap is not fixed: in summer the session runs 16:30–23:00, in winter 17:30–00:00.

Regular trading hours

Summer (mid-March to early November): 16:30 – 23:00. Winter: 17:30 – 00:00. On half days the close is 13:00 in New York — 20:00 in summer, 21:00 in winter.
