Data Correction Notice

NYSE and SIFMA-US holiday status, July 3, 2026

Published 2026-07-03 · Status: Fixed

What happened

For part of the day on Friday, July 3, 2026, the API returned an incorrect status for the NYSE, AMEX, NASDAQ, and SIFMA-US calendars. Queries for that date returned early_close when the correct status is full_close — those markets were fully closed, not on a shortened session.

Why it happened

Independence Day (July 4, 2026) falls on a Saturday this year. When that happens, NYSE and SIFMA-US observe the holiday on the preceding Friday (July 3) as a full market closure, and the early-close session shifts back to Thursday, July 2. Our 2026 holiday data had not accounted for that weekend shift.

We found and corrected the same class of error for December 24, 2027: Christmas Day 2027 also falls on a Saturday, so it is observed Friday, December 24, 2027 as a full closure, with the early close shifting back to Thursday, December 23, 2027.
