PHP Calendar Application

Chronos is a personal calendar and event management web application built for Washington University's CSE 503S rapid-prototyping course. It centers on an interactive month-view dashboard where users can create, edit, and categorize appointments (Work, Personal, Social, Other), with client-side filtering for instant views without page reloads, plus a profile page with productivity analytics over past events.

The backend runs on PHP 8.4 with a MySQL database, using prepared statements throughout to prevent SQL injection, alongside CSRF protection, password hashing, and hardened sessions. The frontend is vanilla HTML, CSS, and ES6 JavaScript with a dark, glassmorphic visual style.

Highlights

• Interactive month-view calendar with categorized event management
• Instant client-side filtering by event category
• CSRF protection, prepared statements, and hashed/session-hardened authentication
