Catarchic astrology, which pertains to beginnings or sources, operates by determining whether a specific, chosen moment is astrologically conducive to the success of an activity initiated at that time.1

Rather than focusing on the fixed circumstances of a birth chart, this practice allows individuals or corporate bodies to select favorable times to act. By aligning the start of an endeavor with auspicious celestial configurations, practitioners aim to bypass potential failures that might otherwise be predicted by an individual's birth chart or a group's moment of origin. In the Indian tradition, this form of astrology is specifically referred to as muhurta-shastra, where a muhurta represents a period of approximately 48 minutes used to identify these opportune moments.12

Ultimately, catarchic astrology functions as a tool for agency, providing a method to navigate the future by strategically timing the commencement of important actions.1
