About
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.
