Waaberi (Time of Day)

Waaberi is the period of early morning when light appears in the eastern sky before and around the time of sunrise. The term is used with two meanings: one referring to the time of dawn (the light that appears before sunrise), and another referring to the moment when the sun becomes visible on the horizon.

From an astronomical perspective, sunrise is the first moment when the upper edge of the sun's disk appears above the eastern horizon. This time is not fixed; it changes with the location on Earth (latitude and longitude), the season, and the elevation of the location.

How the Time Changes

The primary cause of change is the tilt of Earth's axis and Earth's orbit around the sun. In equatorial regions, the variation in waaberi throughout the year is small—day and night are nearly equal. As one moves toward the poles, the difference increases: in summer waaberi comes earlier, in winter it comes later. In regions far from the equator, there are seasons when the sun does not set or does not rise.

Twilight

Before the sun rises, the atmosphere scatters light, causing the sky to brighten while the sun is still below the horizon. This twilight phase is divided into stages (a natural dawn, a nautical dawn, and an astronomical dawn), measured by how many degrees below the horizon the sun lies. Waaberi also has a reddish and orange hue, because when light passes through the atmosphere, it takes a longer path, and blue wavelengths are mostly scattered away.

Religious and Social Uses

Waaberi holds a significant place in Islamic practice and in daily life among Somali people. In Islam, the dawn prayer is performed between dawn and sunrise, and the start and end of the daily fast are tied to the times of dawn and sunset. Somali farmers and herders use waaberi to mark the beginning of the day's work, such as watering animals and milking.
