Calendario Perpetuo

This simple application allows you to store events and anniversaries by specifying the periodicity of the event in various ways:
- indicating a complete date
- indicating the day and month
- indicating only the month
- indicating only the day of the week

Events are shown month by month and are categorized by event type.
There are some types of events, but you can always insert new ones.
Once an event has been entered, it is also possible to specify the days of notice that you want to have and the days of post-warning, i.e. the days following the event during which the event will still be shown, even if already passed.
If you do not specify these fields, the notice will be shown only on the date, month and day indicated.

Note: if you indicate the day of the week, the days of notice and post-warning are used only to indicate respectively that you want to be warned the day before the event and that the warning will also be displayed the day after the event itself.

Functionality
- Insertion / modification / deletion of an "Event type"
- Insertion / modification / elimination of an "Event"
- Search for "Events"
- Export: it is possible to export the events stored in the app to a .csv file. In this way you can have a backup of the data and the possibility to manage it with other programs such as Excel, LibreOffice Calc, ....
- Import: it is also possible to import data from a suitably constructed .csv file (just respect the structure of the one created during the export phase). In this way, in case of problems, it will be possible to recover previously saved data.

Warning: the import will delete all the data in the app and replace them with the imported ones
