📅 Cycle Calendar Generator (iCalendar Format)

This Python project is a specialized utility designed to predict and export health-related cycles into a standard calendar format. It was developed as a practical exercise for the Digital and Computer Sciences (NSI) French Baccalaureate.

Overview

The application calculates future dates for a 28-day cycle and generates a file compatible with the iCalendar (RFC 5545) standard. This allows users to import their data directly into digital calendars like Google Calendar, Outlook, or Apple Calendar.

Key Features

• Date Arithmetic Engine: A custom implementation to handle date additions, accurately managing:
  • Transition between months of different lengths (30 vs 31 days).
  • Leap year calculations for February (28 vs 29 days).
  • Year-end transitions.
• Cycle Prediction: Automatically generates recurring events for a 100-day period based on an initial date.
• iCalendar Export: Formats data into the VCALENDAR standard, including VEVENT blocks for seamless integration.
• Validation Suite: Includes unit tests using assert and integration testing with the ics library to ensure data validity.

Technical Stack

• Language: Python 3.x
• Libraries: calendar (for leap year logic), ics (for validation).
• Key Concepts: Logic Gates, While-Loop Iteration, Tuple Unpacking, String Formatting, and Data Serialization.
