Two rare lunar events are set to light up the skies in 2025 — a Blue Moon and a total lunar eclipse. Whether you’re an astronomy enthusiast or just love gazing at the night sky, these are dates you won’t want to miss.
What Is a Blue Moon?
A Blue Moon isn’t about colour — it’s about timing.
Two types exist:
Monthly Blue Moon: The second full moon in a single calendar month.
Seasonal Blue Moon: The third full moon in a season with four full moons.
They occur roughly every 2–3 years, inspiring the phrase “once in a blue moon.”
Next Blue Moon dates:
May 31, 2026 → Monthly Blue Moon
May 20, 2027 → Seasonal Blue Moon
When Is the Next Lunar Eclipse?
A total lunar eclipse — often called a Blood Moon — occurs when the Earth passes directly between the Sun and the Moon, casting a reddish glow over the Moon’s surface.
Main 2025 Eclipse Details:
Date: September 7–8, 2025
Peak Time in Chennai, India: ~11:41 PM
Duration: 8:58 PM (Sept 7) to 2:25 AM (Sept 8)
Another total lunar eclipse will follow soon after:
Date: March 2–3, 2026
Visible Across: Parts of Asia
Where Can You See It?
India: Chennai and many other cities will see the full September 2025 eclipse.
Worldwide: Asia, Africa, Australia, Europe, and Indian Ocean islands will have great views.
Equipment: None needed — just clear skies and an open spot.
Why Watch?
Blue Moons offer a rare calendar quirk.
Lunar Eclipses transform the Moon into a glowing red orb — a sight that’s both scientific and poetic.
These events are perfect for stargazing parties, photography, or simply a quiet night outdoors.
