Planetary Hours — Chandīgarh

The Chaldean order — Shani (Saturn), Guru (Jupiter), Mangal (Mars), Surya (Sun), Shukra (Venus), Budh (Mercury), Chandra (Moon) — reflects decreasing mean geocentric distance in the pre-Copernican model. Hour 1 of each weekday belongs to its ruling planet; Hour 2 goes to the next in Chaldean descending order, cycling continuously. After Hour 24 the chain lands on the planet that will rule Hour 1 of the following weekday.

Among Vedic Muhurta practitioners the first Hora of the day — ruled by the weekday's planet — is most potent. For other tasks: Sun and Jupiter hours support auspicious, public-facing activity; Venus and Mercury hours are excellent for intellectual and creative work; Moon hours benefit family and emotional matters; Rahu, Mars, and Saturn hours are used cautiously for new ventures, though Mars is productive for physical and technical work.
