Burj

 The Lunar Mansions (Manāzil al-Qamar) are the Buruj mentioned in the Qur'an, forming an ancient system of dividing the sky into 28 segments based on the Moon’s motion, which also underpins the Universal Hijri Calendar. As the Moon traverses the ecliptic over the course of a solar year, it appears to pass through these lunar sectors in succession, completing twelve full cycles around the Earth, one for each Hijri month.

It is interesting to know that, though observational data shows the movement of the moon in the belt of constellations, precise calculations suggest that the sun traverses the same path over the year (365.25 days app.) apparently, the sun lodges in each mansion for approximately 13 days.

This interactive simulation visualizes the Sun’s apparent motion along the ecliptic throughout the solar year, as observed from Earth. The elliptical path represents the ecliptic plane, along which the Sun appears to travel. Surrounding the central Earth are the 28 Manāzil al-Qamar (lunar mansions), traditional markers used in Islamic astronomy to divide the Moon’s monthly journey. As the simulation progresses, the Sun moves along the orbit, illustrating its changing position relative to these celestial landmarks over time. This provides an intuitive, visual understanding of both the Sun’s annual path and the connection between solar motion and classical lunar mansion systems.
