Phases of the Moon

The Moon makes no light — we only see its sunlit half. Waxing = growing, Waning = shrinking. One full cycle takes about 29.5 days.

🌏 In real life

On Karva Chauth or Eid, people watch for the thin crescent moon — that sliver is just the small sunlit part of the Moon we can see from Earth that night.

📝 Quick notes

  • The Moon does not produce its own light; it reflects sunlight.
  • Phases depend on how much of the Moon's sunlit half faces Earth as it orbits.
  • Order: new Moon (not visible) → waxing crescent → first quarter → waxing gibbous → full Moon → waning gibbous → last quarter → waning crescent.
  • Waxing = the lit part is growing; waning = the lit part is shrinking.

🎯 Test yourself

Does the Moon produce its own light?

No — it reflects light from the Sun.
