Formula and Logic Behind the Calculator
The Birth Date Moon Phase Calculator is based on astronomical lunar cycle calculations.
Lunar Cycle Basics:
- One full lunar cycle = 29.53 days
- Moon changes phase as it orbits Earth
Core Calculation:
Lunar Age = (Birth Date − Known New Moon Reference Date) mod 29.53
Phase Determination:
- 0–1 days: New Moon
- 2–6 days: Waxing Crescent
- 7–8 days: First Quarter
- 9–13 days: Waxing Gibbous
- 14–15 days: Full Moon
- 16–21 days: Waning Gibbous
- 22–23 days: Last Quarter
- 24–29 days: Waning Crescent
Practical Example
User Input:
- Birth Date: 15 August 2005
Step 1: Lunar Calculation
Assume lunar age = 14.2 days
Step 2: Phase Identification
14.2 days corresponds to Full Moon phase
Step 3: Output:
- Moon Phase: Full Moon
- Illumination: ~99%
- Lunar Age: 14.2 days
Final Result:
The user was born under a Full Moon.
