Calendar
20 APIs
Calendar APIs return public holidays, observances, name days and religious calendars, and connect to user calendars to read or create events. Holiday data is easy to get wrong across regions, so check that the API covers subdivisions such as states or provinces if you need them. Reading a user's calendar requires OAuth.
Nager.Date returns public holidays for many countries without a key, and UK Bank Holidays is the official GOV.UK feed. Calendarific and Festivo Public Holidays need a key, Hebrew Calendar converts dates and returns Jewish holiday and Shabbat times, and Google Calendar manages events through OAuth.
