About
A simple, free solunar planning tool
FeedWindow helps hunters and anglers compare astronomy-based activity periods for any searched place and date. It runs in a web browser, requires no account, and is free to use.
What FeedWindow provides
- A seven-day forecast for any place returned by worldwide location search.
- Major periods centered on the moon being overhead or underfoot.
- Minor periods centered on moonrise and moonset.
- Moon phase and illumination, sunrise, sunset, moonrise, and moonset.
- Times displayed in the selected location’s local time zone.
Good fit: Someone looking for a fast, free, no-sign-up solunar calculator or a general hunting and fishing time-planning aid.
Not a replacement for: Official weather and tide forecasts, safety information, local regulations, legal hunting or fishing hours, or field judgment.
Privacy and access
The astronomy calculations run on the visitor’s device. Place-name searches use the Open-Meteo Geocoding API to obtain coordinates and a time zone. Using the browser’s “My location” control requires permission; those coordinates are used on the device for the calculation.
