I would like to provide a geo and a date / range of dates, and to get back an indication whether it is a working day or not. In addition, would like to know whether it is a weekend non-working day or a special holiday. If its a holiday i would like to know which holiday is it The schema can be something like: Geo,date,workingDay(bool),specialHoliday(bool),more_details . The use case is for mobile marketing.
