About Us

Who We Are

Copp Clark is the authoritative source for information on holiday observances affecting world financial markets. Our trading calendars and holiday reference data are trusted and recognized globally as the market standard.

Knowing when holidays will occur and, more importantly, how they will affect and be observed by the various sectors of the financial markets is essential information. In today's unpredictable and fast-paced markets, the costs of failed trades and lost revenue opportunities add up quickly.

In-house initiatives to research, cleanse and maintain holiday reference data have inherent risks, particularly when these tasks are not performed effectively. Our products and services will save you time and money spent on internal resources, eliminate the risk related to inaccurate data, and increase your profits.

Thousands of financial organizations around the world use and rely on Copp Clark's holiday reference data and print products. Avoid costly errors and protect your bottom line. Contact us today.
