Holiday Data Service® for Financial Applications

COPP CLARK’S HOLIDAY DATA SERVICE® is the preferred solution by clients that need reliable and accurate holiday reference data in their systems.

In today’s unpredictable and fast-paced markets, it is essential to know when holidays will occur and what their impact will be.

With timely and accurate information, you can reduce the risk of an extra day’s interest paid, a failed trade, or unnecessary administrative expense.

Copp Clark keeps you informed.
Holidays and trading hours for many exchanges are in constant flux and require continuous monitoring. Holidays are revised regularly, often on very short notice.

In-house initiatives to research, cleanse and maintain this data represent a significant business expense and come with inherent risks, particularly when conducted without sufficient expertise.

That’s why financial organizations around the world look to Copp Clark for a reliable, cost effective solution.

While some sources only list general financial holidays, Copp Clark specifies what each holiday affects: currency, bank, exchange trading, exchange settlement – the details that matter.

Copp Clark is the authoritative source for holiday reference data relating to global financial markets.

Subscribing to Copp Clark’s Holiday Data Service® provides industry-standard holiday and trading hours reference data with outstanding customer support, for one low annual fee.

Here’s how it works.
Holiday Data Service® clients receive a complete set of holiday data files covering all the market sectors, extending as many years forward as required. These files are delivered by secure FTP in standard (xls, txt, csv, xml), custom or vendor-specific formats.

Throughout the year, our experienced team monitors changes to holidays and hours of operation affecting markets around the world. When there is a confirmed change to an observation, clients are notified; replacement files are delivered.

All subscriptions include 24/7 access to, a handy quick-reference website that is maintained and updated daily, providing information on holidays for every currency, more than 400 exchanges and all major financial centres around the world.
