The API returns the number of days, hours, working days, working hours, wages, weekend days, and the list of public holidays of the requested date period and country. You can also add any number of working days or working hours to a given date. 52 countries and over 270 regional calendars are currently supported and we work hard to keep our database up to date by following government announcements regarding public holidays changes. All the calendars can be fully customized from our friendly working days websites' user interfaces. Data is returned in JSON format. This service is hosted on the professional cloud OVH.
