How this service works
Use when an agent needs to know if a stock exchange trades on a given day (default today) before scheduling orders, reports or alerts. 28 exchanges incl. NYSE, Nasdaq, LSE, Xetra, Euronext, SIX, Tokyo, HKEX, Shanghai, ASX. Returns holiday name, hours in local time + UTC, half days, lunch breaks, pre/after-market (Nasdaq, Xetra), live status, next open/close, previous/next trading day. Official exchange calendars only; bad input: HTTP 400, no charge.
Output
A JSON object indicating whether the exchange trades on the requested date, any applicable holiday name, opening and closing times in both local and UTC, half-day flags, lunch break windows, pre-market and after-market session times where available (Nasdaq, Xetra), current live open/closed status, and the dates/times of the next and previous trading days.
Example use cases
Pre-trade scheduling check
“I'm about to schedule a batch of limit orders for XLON — can you confirm whether the London Stock Exchange is open this Friday and what the trading hours are in UTC?”
Holiday-aware alert system
“My alert system fires every weekday morning — is the Tokyo Stock Exchange (XTKS) open today, or is it a Japanese holiday I should skip?”
Post-holiday next trading day lookup
“The ASX was closed yesterday for a public holiday — what's the next trading day and when does it open local time?”
Technical details
Endpoint
GEThttps://handelskalender-api.pages.dev/v1/trading-day?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to check a single day's trading status for a specific exchange before executing time-sensitive operations like order scheduling, report generation, or alert dispatch. It is ideal for real-time or near-real-time decisions. Use the annual calendar sibling endpoint instead when you need bulk holiday data for an entire year, or the live status sibling when you want a snapshot of all exchanges open right now.
Side effects
- HTTP 400 returned for unrecognized exchange codes or malformed date strings
- No charge is applied on bad input
- Exchanges not in the supported list of 28 will return an error
- Future dates beyond calendar data availability may return incomplete results
