Our range of API services with high data quality enables developers and businesses to access several databases—and use the Time and Date calculators.
All API services are offered in packages. Every package grants access to a different range of services or data points and contains a number of credits. Credits are used to count the requests your software can make, for example to access a database. Mix and match our packages to suit your business needs.
For more than 20 years, Time and Date has employed and partnered with researchers, scientists, and journalists to keep our databases always up-to-date. We use credible sources like governmental records, scientific journals, and local legislation.
For astronomical calculations, we use algorithms developed by the US Naval Observatory and NASA's Jet Propulsion Laboratory.
This is why Time and Date has become a reliable and trusted source used by organizations and developers around the world.
