Sky Calendar works out every eclipse, meteor shower, aurora, ISS pass and dark Milky Way night for your city through 2076. Each event comes with local times, where to look and how high it will be, plus tonight's clouds and darkness at a glance and a reminder before it starts. Aurora nowcast, a map of dark observing spots, an AR sky finder and an astronomer mode with Bortle, SQM and red night vision.
Hi Product Hunt 👋
I kept missing things in the sky. A meteor shower peak I heard about the next morning, an ISS pass behind clouds, an aurora night when I was looking the wrong way. Most astronomy apps are star charts; I wanted a calendar that tells me what is happening over my city, when, and whether I'll actually see it.
So I built Sky Calendar:
Events for your city — solar and lunar eclipses (with the path on a map), meteor showers, full moons, planets, ISS passes, bright comets and Milky Way nights, computed for 371 cities through 2076.
Tonight — cloud layers, fog, darkness and what's up, at a glance.
Northern lights — NOAA Kp forecast plus a 30-minute nowcast, with an alert when the aurora may be visible from you.
Where to watch — a map of observing spots near your city, from parks to dark-sky sites.
Find it — point your phone at the sky and the AR view shows where to look.
Astronomer mode — Bortle, SQM, ZHR, azimuth/altitude, and a red night mode for dark-adapted eyes.
Reminders, widgets, Live Activities for eclipses and the next 12 months of events are free forever. Plus unlocks the planning tools.
The big one coming up: the total solar eclipse of 2 August 2027 across Spain and North Africa — the app is ready for it.
I'd love to hear which sky events you never want to miss, and what's missing for you. Clear skies! ✨
