About WhenToStargaze

WhenToStargaze answers one question: is tonight worth looking up where you are? Instead of a wall of numbers, every location page leads with a plain-English verdict, then backs it with the details — moon phase, how long the sky stays truly dark, which planets are up, and the best nights coming.

How it works

• Astronomical data (moon, sun, twilight, planets, eclipse circumstances) is computed from established models for your exact coordinates.
• The live cloud forecast comes from Open-Meteo and updates through the day.
• We cover thousands of towns and cities worldwide, plus a calendar of upcoming events — the famous ones and the overlooked ones.

Honest by design

We'll happily tell you when tonight is poor — a bright Moon or cloud means a wasted trip. The goal is to save you the drive, not to hype every night.
