In Indian astrology, muhurta-shastra serves as the primary system of catarchic astrology, which focuses on identifying the most auspicious moments to begin specific actions.1

Within a single day, time is divided into 30 units known as muhurtas, each lasting approximately 48 minutes. Astrological experts analyze the relative celestial positions of planets and nakshatras (lunar mansions) during these intervals to determine whether a specific time is favorable or unfavorable for an activity.21

Practitioners are consulted to identify these optimal muhurtas for significant life events and undertakings, including:
* Solemnizing a marriage2
* Performing a puja (ritual offering)2
* Starting a business2
* Moving into a new home2
* Beginning a journey2

Because these astrological reckonings are localized, the specific muhurta depends on the geographic location of the event. By selecting these favorable windows, individuals seek to align their actions with celestial conditions to enhance the likelihood of success, a practice that inherently allows for agency in navigating one's circumstances.23
