## Overview

MoodJournal is a PHP/MySQL personal journaling app. Users enter through the home page, record or update a daily mood and note from the calendar, then review entries in history or mood-distribution statistics. The sampled source confirms the calendar, history, statistics, JSON API, and MySQL access paths; no authentication or other future features are represented.

Main entry points: [`api.php`](https://github.com/priyankakeshava/moodjournalcalendar/blob/main/api.php) (Mood API), [`index.php`](https://github.com/priyankakeshava/moodjournalcalendar/blob/main/index.php) (Calendar page), [`home.php`](https://github.com/priyankakeshava/moodjournalcalendar/blob/main/home.php) (Home page), [`script.js`](https://github.com/priyankakeshava/moodjournalcalendar/blob/main/script.js) (Calendar interaction)
