This application allows you to view the Repsol Petroleum and Chemistry quadrants of the Tarragona CI.
When you start the application for the first time, you choose one of the two options (petroleum or chemical).
Once chosen, the list of months of the year is displayed.
When you choose a month, the quadrant of the chosen area is shown.
You can move backwards and forwards in the months and in this way be able to see the quadrants and know in which shift you will work in the visible periods throughout the year in which the application is updated.

It is possible to change options and view the quadrants of the option not initially chosen.
