- How we calculate this
- The market schedule is calculated in Asia/Tokyo, then translated into Europe/Paris for Paris. Holiday closures and next-session labels use the same exchange calendar model as the main JPX Tokyo page.
- Data sources
- JPX domestic trading hours, JPX / trading calendar, the IANA Time Zone Database, and the curated city catalog used for canonical city routes.
- Update cadence
- Market-city pages revalidate every 15 minutes; live open/closed labels are request-time snapshots. The model covers regular sessions and curated full-day closures, while half-days, halts, auctions, and emergency notices require official confirmation.
