Sunset Sunrise Times iPhone: How to Get Them
To get sunset and sunrise times on an iPhone, you can use the built-in Weather app, which shows daily sunrise and sunset times for your current location, or ask Siri. You can also add a dedicated widget to your Home Screen for at-a-glance times, or use the Clock app’s World Clock feature for specific cities.
Background: Why Sunrise and Sunset Times Matter
Knowing when the sun rises and sets is useful for more than just planning a scenic photo. Photographers use the “golden hour” (the period shortly after sunrise and before sunset) for soft, warm lighting. Gardeners track daylight hours for planting and watering schedules. Commuters and runners may plan their routes around daylight for safety. Even casual users check sunset times to know when to start evening activities or when to expect darkness for stargazing.
Apple has integrated this data into iOS for years, but the exact location of the information has changed with different iOS versions. In older versions, you had to rely on third-party apps or the Weather Channel widget. Since iOS 16, the Weather app has become much more comprehensive, offering hourly and daily forecasts with sunrise and sunset times built in.
How the iPhone Gets Its Sunrise and Sunset Data
The iPhone calculates sunrise and sunset times using a combination of your device’s GPS location and a mathematical model of the Earth’s orbit and tilt. The calculation is not a simple lookup; it’s a precise astronomical algorithm that accounts for:
- Latitude and longitude: Your exact position on Earth determines the sun’s path across the sky.
- Date and time zone: The Earth’s position in its orbit changes daily, and your time zone affects how those times are displayed.
- Atmospheric refraction: The atmosphere bends sunlight, so the sun appears above the horizon a few minutes before it actually rises and after it sets. The iPhone’s calculations typically assume a standard refraction of 0.833 degrees, which is why the times may differ slightly from a purely geometric calculation.
Apple uses the same core astronomical data that powers the built-in compass and Maps’ sun position feature. The times are generally accurate to within a minute or two for most locations.
Method 1: Using the Built-in Weather App
The simplest way to get sunrise and sunset times is through the Weather app, which comes pre-installed on every iPhone.
- Open the Weather app.
- Ensure you are viewing the forecast for your current location (or add a city by tapping the list icon in the bottom-right corner and searching).
- Scroll down past the hourly and 10-day forecast sections.
- Look for the Sunrise and Sunset entries, typically shown as a row with a sun icon and the times in your local time zone.
In iOS 16 and later, you can also tap on the sunrise or sunset time to see a graphical representation of the sun’s path across the sky for that day.
Method 2: Ask Siri
Siri is the fastest method if you just want a quick answer. You can say:
- “Hey Siri, what time is sunset today?”
- “Hey Siri, when does the sun rise tomorrow?”
- “Hey Siri, what time is sunset in Paris?”
Siri will respond with the time for your current location by default, unless you specify a city. This works even if you have not granted the Weather app location access, as Siri uses your device’s location services.
Method 3: Adding a Home Screen Widget
If you want the times visible without opening an app, you can add a widget to your Home Screen or Lock Screen.
- Touch and hold a blank area on your Home Screen until the apps jiggle.
- Tap the + button in the top-left corner.
- Search for the Weather widget (it may be under the “Weather” category).
- Swipe through the available widget sizes. Some sizes show sunrise and sunset times directly; others may require you to scroll within the widget.
- Tap Add Widget, then position it and tap Done.
On the Lock Screen (iOS 16 and later), you can add a small weather complication that shows the current temperature, but it typically does not display sunrise/sunset times directly. For that, you would need a third-party widget.
Method 4: Using the Clock App for Other Cities
The Clock app’s World Clock feature is useful if you need sunrise and sunset times for a specific city, especially when planning travel or calls with people in different time zones.
- Open the Clock app.
- Tap the World Clock tab at the bottom.
- Tap the + button in the top-right corner.
- Search for a city and select it.
- Tap on the city name in the list to see its details, which include the current time, date, and sunrise/sunset times.
Note that this method only shows times for the selected city, not your current location. Also, the World Clock does not show the sun’s path or other weather details.
Common Problems and Misconceptions
A common issue is that the Weather app shows the wrong times for your location. This usually happens because the app is using a different location than your current one. Check that the location services are enabled for the Weather app: go to Settings > Privacy & Security > Location Services and ensure Weather is set to “While Using the App” or “Always”.
Another misconception is that the times are “wrong” when they differ from a printed almanac or a website. As mentioned, the iPhone uses a standard refraction value, but some sources use a slightly different one or account for local terrain (e.g., mountains blocking the horizon). For most practical purposes, the difference is negligible.
If you are in a location with extreme latitudes (near the poles), the sun may not rise or set for days. The Weather app will show “No sunrise” or “No sunset” in these cases, which is correct.
Alternatives to the Built-in Features
While the built-in tools are sufficient for most users, third-party apps offer more specialized features:
- Photography apps: Apps like Sun Surveyor or PhotoPills provide augmented reality overlays showing the sun’s exact path, golden hour times, and blue hour times.
- Weather apps with more detail: Some weather apps, like Carrot Weather or Weather Line, present sunrise and sunset times with more visual flair and additional data like UV index.
- Websites: Websites like timeanddate.com provide very precise sunrise and sunset times for any location, including civil, nautical, and astronomical twilight times, which the iPhone does not show by default.
For most everyday needs, the built-in Weather app and Siri are more than enough. The third-party apps are only necessary for niche use cases like professional photography or astronomy.
Frequently Asked Questions
Why does the Weather app show a different sunset time than a website?
Small differences (1-3 minutes) are normal due to the exact atmospheric refraction model used and the precise location coordinates. The iPhone uses a standard model, while some websites may use a more precise one that accounts for local elevation or the actual horizon.
Can I get sunrise and sunset times for a future date?
The Weather app only shows times for the current day and the next few days in the 10-day forecast. For a specific date months in advance, you would need a website like timeanddate.com or an astronomy app.
Does the iPhone show civil twilight times?
No, the built-in Weather app only shows the official sunrise and sunset times. It does not show civil, nautical, or astronomical twilight. Third-party astronomy apps do provide these.
Why does the sunrise time change so much between summer and winter?
The Earth’s axial tilt of about 23.5 degrees causes the sun’s path across the sky to vary seasonally. In summer, the sun rises earlier and sets later in the Northern Hemisphere, while in winter it does the opposite. The effect is more pronounced at higher latitudes.
Is the sunrise time in the Weather app based on my exact GPS location?
Yes, the Weather app uses your device’s GPS coordinates to calculate the times. If you are in a large city, the times will be for your precise location, not the city center, which is why they may differ slightly from a city-wide forecast.
