The task:

Create a small WEB API application that returns country public holidays.

Requirements for the Application:

1. Endpoints to implement:

- countries list

- grouped by a month holidays list for a given country and year

- specific day status(workday, free day, holiday)

- the maximum number of free(free day + holiday) days in a row, which will be by a given country and year

2. Endpoints should return JSON as a response.

3. To get a data(countries, holidays) your application should use a JSON API from https://kayaposoft.com/enrico/. Your application should avoid repeated requests to a https://kayaposoft.com/enrico/. Results from a https://kayaposoft.com/enrico/ should be normalized and saved to a database, so next time your application should query a database.
