Question 1

How many hours of daylight does Lyon get today?

Accepted Answer

Lyon currently gets approximately 13 hours and 7 minutes of daylight today. This varies throughout the year — days are longest around the summer solstice (June in the Northern Hemisphere, December in the Southern Hemisphere) and shortest around the winter solstice. At 45.8° latitude, Lyon sees moderate variation, with summer days noticeably longer than winter days. Our calculations use the SunCalc astronomical library for accuracy within 1–2 minutes.

Question 2

What time does the sun rise in Lyon?

Accepted Answer

Sunrise times in Lyon change throughout the year based on the Earth's axial tilt and the city's position at 45.8° latitude. Use the table above to see today's exact sunrise time, as well as dawn (civil twilight) and other twilight phases. The earliest sunrise typically occurs around the summer solstice, while the latest sunrise happens near the winter solstice. The difference between earliest and latest sunrise can be over two hours. All sunrise calculations are based on NOAA solar position algorithms via the SunCalc library.

Question 3

What time does the sun set in Lyon?

Accepted Answer

Sunset times in Lyon vary by season due to the Earth's orbital mechanics and the city's latitude of 45.8°. Check the table above for today's exact sunset time, including dusk and twilight phases. The latest sunset typically occurs a few days after the summer solstice, while the earliest sunset happens a few days before the winter solstice. At mid-latitudes, you can expect sunset to vary by 2–3 hours across the seasons.

Question 4

How does day length change throughout the year in Lyon?

Accepted Answer

Lyon at 45.8° latitude experiences moderate seasonal day length variation. Summer days are noticeably longer than winter days, with daylight typically ranging from about 8 to 16 hours depending on the time of year. The rate of change is fastest around the equinoxes (March and September), when day length changes by several minutes each day. Around the solstices, the rate of change slows as day length approaches its maximum or minimum. This makes spring and autumn the seasons with the most noticeable daily changes in sunrise and sunset times.

Question 5

What is civil twilight in Lyon?

Accepted Answer

Civil twilight in Lyon is the period when the sun is between 0° and 6° below the horizon. During civil twilight, there is enough natural light for most outdoor activities without artificial lighting. It occurs just before sunrise (dawn) and just after sunset (dusk). At mid-latitudes, civil twilight typically lasts about 25–35 minutes. The exact duration for Lyon is shown in the twilight data table above.

Question 6

What are the different twilight phases?

Accepted Answer

There are three twilight phases, each defined by the sun's angle below the horizon. Civil twilight (0°–6°) is the brightest phase, with enough light for outdoor activities without artificial lighting. Nautical twilight (6°–12°) is dimmer but still allows sailors to see the horizon for celestial navigation. Astronomical twilight (12°–18°) is nearly dark, with only the faintest glow on the horizon, and most stars become visible. Below 18° is considered full astronomical night. The duration of each phase varies by latitude and season — our data table above shows all twilight phases for Lyon.

Question 7

When is the longest day in Lyon?

Accepted Answer

The longest day in Lyon occurs around the summer solstice. For Lyon in the Northern Hemisphere, the longest day is around June 20–21. On this date, Lyon experiences its earliest sunrise and near-latest sunset of the year. At 45.8° latitude, the longest day is typically 14–16 hours of daylight. The shortest day (winter solstice) occurs approximately six months later.

Question 8

Does daylight saving time affect sunrise and sunset times in Lyon?

Accepted Answer

Yes, when Lyon transitions to daylight saving time, clock-based sunrise and sunset times shift by one hour. However, the actual amount of daylight doesn't change — DST simply moves an hour of daylight from the morning to the evening. This means sunrise appears one hour "later" on the clock during DST, and sunset appears one hour "later" as well. The transition typically causes a noticeable jump in the sunrise/sunset table around the spring and fall changeover dates. Check our DST change calendar for exact transition dates in Lyon.
