Each and everyone of us look for auspicious days (शुभ मुहूर्त) to do special things like declaring marriage date, naming your new born baby, buying car, etc.

If we talk about Hindu religions, Shukla paksha (शुक्ल पक्ष) and Krishna paksha (कृष्ण पक्ष) mean a lot in the context of Shubh Muhurt. What is the theory behind these two pakshas? How can one choose a shubh day between these two periods? Lets get to know the answer of these questions.

The Moon revolves around the earth. The time it takes for one complete revolution is called as a Lunar month (चन्द्र मास). The Lunar month, in general, is of 29 days, 12 hours, and 44 minutes.

What is a Paksha?

Each Lunar month is divided into two pakshas. A paksha is a lunar fortnight, or a period of approximately 14 days. As most of the Hindi speaking people know, the literal meaning of the work ‘Paksha’ is side. A paksha in the context of this article means a side of a month – either on the Shukla’s side or the Krishna’s.

Shukla Paksha & Krishna Paksha differentiation

If we know the meaning of the Sanskrit words Shukla and Krishna, we can easily differentiate between the two pakshas. Shukla means bright, whereas Krishna stands for dark.

A Shukla paksha is from the new moon (Amavasya) to the full moon (Poornima). Whereas, Krishna paksha, opposite of the Shukla paksha, starts from the full moon to new moon. In short, Shukla paksha is the period of bright or waxing moon; whereas Krishna paksha is the time when moon fades.

Shukla & Krishna Paksha

Which one is auspicious? Which not?

Generally, people consider Shukla paksh as auspicious and Krishna paksha as inauspicious. Obviously, this consideration is due to the energy and brightness of the moon.

But as per the Astrology, the period from the 10th day of Shukla paksha to the 5th day of Krishna paksha is considered astrologically auspicious. In this period of time, the energy of the moon is maximum or nearly maximum – that plays an important role in Astrology to decide good (shubham) and bad or inauspicious (ashubh) days.
