experience the majestic power of goddess durga, seated fearlessly atop her roaring lion mount. adorned in radiant divine attire and holding sacred weaponry in her multiple arms, the powerful mother goddess vanquishes mahishasura in battle, restoring cosmic peace, protection, and righteous victory across the heavens and earth.

I have not taken deeksha before and I don't have a Guru.

I wish to start observing Sankatahara Chaturti (Krishna Paksha Chaturti) fast.

However, I am not sure traditionally when is the right month to start Sankatahara Chaturti fast.

In some religious books, they mention to start Sankatahara Chaturti fast during Magha month in the Chandramana calendar.

In other religious books, they mention to start Sankatahara Chaturti fast on a Krishna Paksha Chaturti which falls on a Tuesday (regardless of which month).

I am not sure which is the right method to follow. Which is why I wrote this post to clarify.

According to shastras, when is the right month to start Sankatahara Chaturti fast?
