Industry-standard data: The Q++ Project
was started in 1989, at the request of a group of diary publishers, with the aim to create software tools
allowing for the long-term prediction of worldwide public holidays. Initially released in 1999, the Q++ Worldwide
Public Holidays Database has now become the reference source of worldwide public
holidays used by the world's foremost diary publishers.
Coverage of the entire world:
The Q++ Worldwide
Public Holidays Database covers all 195 countries of the world as well as all
the semi-autonomous territories of the world (such as Hong Kong, Macau, Greenland, Gibraltar
Uniform coverage of the world:
We have diary publishing clients on all 5
continents, so every single country of the world, no matter how small or how remote,
gets our full attention.
Focus on real
public holidays: Our data is designed for professionals who need to know the
dates of actual public holidays (ie. when either businesses, banks or government
services are closed), and we relentlessly purge our database of any dates that
are not real public holidays.
Since 1989, we have developed mathematical and astronomical software libraries,
in cooperation with world-renowned calendar experts from Denmark, India, Israel, Saudi Arabia, Singapore, Switzerland and the USA.
These unique software tools, in conjunction with our database of predictive rules, enable us to easily forecast worldwide
public holidays for the next 30 years and beyond.
To identify last-minute changes, and anticipate long-term changes to worldwide
public holidays, we
review hundreds of online news sources and government sites, every single day of
the year . Some of the
highlights of this research are published in our
Worldwide Public Holidays News Updates, which is visited daily by diary and
calendar publishers, banks, financial institutions, logistics companies,
shipping and brokerage firms, government agencies, NGOs, and even other websites.
data formatting: We are professional software developers, and the data files
we supply are designed for maximal
ease and flexibility of import into relational database and ERP systems. We use specific
and consistent keywords to allow you to filter information such as regional or
tentative holidays, and each entry has a unique country and holiday ID, as well
as the date when the public holiday recurrence rule was last modified.
delivery: Licensed public holidays data is available as Excel and/or CSV
files, and updates can be sent to you by email or uploaded to the FTP server of
your choice. In-between updates, you can request email notifications for only
certain countries, or for changes that have an imminent impact (for example,
before the date of the next regular update).

Licensing restrictions are few, and are all couched in plain English.
