The science of Vastu Shastra is all about prioritizing auspicious placements to optimize the energy flow in your life and help you lead a more fulfilling life that’s aligned with your goals and values. Any vastu expert will tell you about the importance of a holistic approach (considering design, orientation, weather, and sunlight) in executing the construction of a building. But there’s more to keep in mind when optimizing your life for good fortune.

Below we’ve organized a guide to help you navigate and determine the auspiciousness of a day according to Vedic Astrology, a vast and intricate science, and Muhurtha, so you can plan your activities accordingly for maximal chances of success.

There are several factors that help determine the auspiciousness of a particular day. Think of planning muhurtha as part of Vastu living. Of these, the four most important ones are below:

a moon in various phases waning from left to right.


To determine the tara of a particular day, you must count from your birth star (janma nakshatra), which is determined by the moon’s position at your time of birth. Count from your birth star to the ruling sign on any particular day and divide that number by 9 to calculate the tara on any particular day. The auspiciousness of a day will depend on this tara. In general, the Janma, Vipat, Pratyak, and Vadha are particularly inauspicious.

Vaara (day of the week)

Perhaps the most familiar elements on the list, certain days of the week are auspicious by default. These include Monday, Wednesday, Thursday, and Friday. Tuesday, Saturday, and Sunday are not auspicious, although their malefic effects greatly diminish after nightfall.


There are two karans in each tithi, and each karan represents a 6-degree movement of the moon. There are 11 karans in total, and each means something different in determining the auspiciousness of a day. The karans Vishti, Chathuspaadam, Nagam, Kimstughnam, and Shakunam are particularly inauspicious and to be avoided.


These have to do with the aspects of planets and houses. Their calculation is intricate and meticulous. Some yogas you should avoid for scheduling any important events are:

Kemadruma Yoga, Parigham, Pyatreepatam Vajram, Shakat, and more, depending on the day of the week (vaara) as well.
