Reliable Data, Dedicated Research

Time and Date algorithms are based on work and data developed by the U.S. Naval Observatory and NASA's Jet Propulsion Laboratory. In other words: We are using data that has been used to send probes to other planets.

Our multilingual team of researchers manually controls the quality and accuracy of our data, while our algorithms calculate holiday dates years in advance. We research holidays around the world using primary sources such as government records, laws, and regulations.
