Seasonal planning
Compare how the sun changes through the year and choose the date that gives a place the light or shadow you want.
Alerts, widgets & Live Activities
Keep upcoming solar moments glanceable and set local alerts when a particular window matters to your plans.
Precise by design
Astronomy first. Guesswork last.
Once a coordinate and timezone are known, Solstice calculates solar position and event timing locally. It handles real local days, daylight-saving changes, and high-latitude conditions without needing a weather-style backend.
