昼夜世界时间

Discover what time it is across the world — and where the day begins and ends. • World clocks: See local dates, live clocks, daylight saving time, and the difference from your current time zone. • Sunrise and sunset: Explore daylight duration and civil twilight for the date you choose, including polar day and night. • Offline city search: Find cities in a bundled global city catalog without sending your search to a server. • Your favorite places: Save, reorder, and remove cities. • Optional location: Find your current locality. You can always search manually without granting location access. • Native experience: Supports light and dark appearances, larger text, and 12- or 24-hour time. • No account, ads, or in-app purchases. City search, saved clocks, and solar calculations work offline. Maps and current-locality lookup use Apple network services. Time depends on your device clock. Solar events are estimates; terrain, elevation, and weather can affect what you see. The app does not provide weather forecasts.
