## What is Gazulation?

Will tonight be worth looking up?

Gazulation answers one question: when is the best time to stargaze from where you stand. It reads the next 12 hours of sky conditions and gives every hour a simple rating — Excellent, Good, Fair, or Poor — so you know at a glance whether to grab your telescope or stay cozy inside.

THE BEST TIME, FOUND FOR YOU
Gazulation weighs everything that matters for a dark, clear sky:
• Cloud cover — the deal-breaker
• True darkness — not just sunset, but astronomical twilight
• The Moon — its position and brightness wash out faint stars
• Humidity and dew — the haze that blurs your view
• Wind — steadiness for telescopes and astrophotography

Then it highlights the single best window tonight, so you don't have to decode a weather chart yourself.

HOUR BY HOUR
See the next 12 hours as a simple timeline. Each hour gets a rating and the details behind it: sky visibility, temperature, humidity, wind, and where the Moon sits.

ANYWHERE ON EARTH
• Use your current location with one tap
• Search any city or place
• Enter exact coordinates for that dark-sky site you love

MADE FOR NIGHT
A calm, dark interface that is easy on adapted eyes.

Whether you are an astrophotographer planning a session, chasing a meteor shower, or just wondering whether to step outside — Gazulation tells you when.
