FAQ about sun movement in Alna

What time is sunrise in Alna today?
Sunrise times in Alna change throughout the year. Check the table above for today's exact sunrise time. Sunrise is when the upper edge of the sun appears above the horizon, accounting for atmospheric refraction.
What time is sunset in Alna today?
Sunset times in Alna vary by season. The table above shows today's exact sunset time. Sunset is defined as the moment the upper edge of the sun disappears below the horizon.
How long is the day in Alna?
Day length in Alna changes throughout the year due to the Earth's axial tilt. In summer, days are longer, while in winter they are shorter. The difference can be significant depending on the city's latitude. Check the day length column in the table above.
What is solar noon?
Solar noon is the moment when the sun reaches its highest point in the sky for the day. It marks the midpoint between sunrise and sunset. Solar noon does not always occur at 12:00 clock time due to timezone boundaries, daylight saving time, and the equation of time.
What are the different types of twilight?
There are three types of twilight: Civil twilight (sun 0–6° below horizon) when there is enough light for outdoor activities; Nautical twilight (sun 6–12° below) when the horizon is still visible at sea; and Astronomical twilight (sun 12–18° below) when the sky is dark enough for astronomical observations. These phases are important for determining Fajr and Isha prayer times.
How does the sun affect prayer times?
All five Islamic daily prayers are determined by the sun's position. Fajr begins at dawn (astronomical twilight). Dhuhr starts after solar noon. Asr is when shadows reach a specific length. Maghrib begins at sunset. Isha starts when twilight disappears. Accurate sun data is essential for correct prayer times.
Why do sun times change with the seasons?
Sun times change because the Earth's axis is tilted at 23.44° relative to its orbit around the Sun. During summer in the Northern Hemisphere, the North Pole tilts toward the Sun, giving longer days. During winter, it tilts away, shortening days. This effect is more pronounced at higher latitudes.
What is the sun's altitude?
The sun's altitude is the angle between the sun and the horizon, measured in degrees. At sunrise and sunset it is 0° (accounting for refraction). At solar noon it reaches its maximum for the day. The maximum altitude depends on your latitude and the time of year.
What is the sun's azimuth?
The sun's azimuth is the compass direction of the sun measured in degrees from north (0° = North, 90° = East, 180° = South, 270° = West). The sun rises roughly in the east and sets roughly in the west, but the exact azimuth varies by season and latitude.
What happens at the equinox?
At the equinoxes (around March 20 and September 22), day and night are approximately equal in length everywhere on Earth. The sun rises almost exactly due east and sets almost exactly due west. After the March equinox, days get longer in the Northern Hemisphere; after the September equinox, they get shorter.

Le mouvement du soleil a une importance centrale pour la prière musulmane.

Sun position and Islamic prayer times

In Islam, the five daily prayers are directly tied to the sun's position in Alna. Fajr begins at dawn when the first light appears on the horizon, before the sun rises. Dhuhr is prayed after the sun passes its highest point (solar noon) and begins to decline. Asr is determined when an object's shadow reaches a specific length relative to the object itself. Maghrib begins immediately after sunset, and Isha starts when the twilight has fully disappeared. Understanding sun movement data helps Muslims pray at the precise correct times.

Seasonal variation in sun times in Alna

Sun times in Alna change dramatically throughout the year at latitude 44.1°. Near the equator, sunrise and sunset times remain relatively stable year-round, with roughly 12 hours of daylight. At higher latitudes, the difference between summer and winter can be extreme — cities in Scandinavia may experience nearly 24 hours of daylight in summer and very short days in winter. This seasonal variation directly impacts prayer schedules, making Fajr very early in summer and quite late in winter for northern cities. The equinoxes in March and September mark the points where day and night are approximately equal worldwide.

Practical uses of sun data

Beyond prayer times, sun movement data in Alna serves many practical purposes. Photographers and filmmakers use golden hour and blue hour calculations to plan shoots. Architects consider sun angles when designing buildings for optimal natural lighting and energy efficiency. Farmers and gardeners use day length data to plan planting schedules. Solar panel owners track the sun's path to maximize energy production. Hikers and outdoor enthusiasts check sunrise and sunset times for safety planning. Astronomers use twilight data to determine optimal stargazing conditions.
