## Overview

This is a small interactive command-line event scheduler, started with `python App.py`. The user enters event details, which are format-checked and stored in an in-memory list; they can then list events, delete by title, or search by date or keyword. Listing sorts by date and time before displaying each event. `Event.py` holds the event record and its formatted display behavior. The README documents only how to launch the app; relationships shown here come from the sampled source.

Main entry points: [`App.py`](https://github.com/njabulorivaldo/event-scheduler-app/blob/master/App.py) (Menu loop), [`Event.py`](https://github.com/njabulorivaldo/event-scheduler-app/blob/master/Event.py) (Format display)
