🌕 Moon-Phase-Calculator

Python-based lunar phase calculation and visualization project

---

🎯 Purpose & Scope

Moon-Phase-Calculator is a Python project designed to calculate and visualize the current phase of the Moon based on a given date. It combines astronomical calculations with simple visualization, suitable for astronomers, photographers, and enthusiasts.

• Calculates the Moon's phase for today or any specified date.
• Displays textual representation of the Moon phase (e.g., New Moon, First Quarter, Full Moon).
• Computes approximate illumination percentage.
• Outputs results in a clear, readable format for easy observation planning.

🧮 Physical / Astronomical Model

• Moon Phase Calculation:

The phase of the Moon is computed based on its age in the synodic month (~29.53 days):

Phase = (Current Date - Known New Moon Date) mod 29.53

Where:

1. New Moon
2. Waxing Crescent
3. First Quarter
4. Waxing Gibbous
5. Full Moon
6. Waning Gibbous
7. Last Quarter
8. Waning Crescent

• Illumination Calculation:

Illumination (%) = (1 - cos(Phase × 2π / 29.53)) / 2 × 100

This approximation provides the visible illuminated fraction of the Moon's disk.
