Why Paksha matters beyond just "the moon was waxing or waning"
Paksha is one of the five limbs of the Panchang (the traditional Hindu almanac), alongside Tithi, Nakshatra, Yoga and Karana, and it's used to judge the auspiciousness of dates for ceremonies and new beginnings — Shukla Paksha is generally favoured for starting new ventures, while Krishna Paksha is often preferred for concluding or letting go of something.
Tithi — the actual lunar day
Within each Paksha there are 15 Tithis (lunar days), each named and associated with its own deity and general character — from Pratipada (the first day of each fortnight) through to Purnima (full moon) or Amavasya (new moon), depending on which Paksha you're in.
Frequently asked questions
What is the difference between Tithi and Paksha?
Paksha is the fortnight (waxing or waning); Tithi is the specific lunar day within that fortnight — there are 15 Tithis in each of the two Pakshas, for 30 Tithis total in a lunar month.
Is a Shukla Paksha birth considered better than Krishna Paksha?
Classical texts describe the two Pakshas as suited to different kinds of undertakings rather than one being universally "better" — Shukla Paksha for growth and new starts, Krishna Paksha for release and completion — rather than ranking one over the other for a birth chart specifically.
Does moon phase affect my zodiac sign?
No — moon phase (Paksha and Tithi) and Moon sign (Rashi) are two separate readings of the same Moon position: the sign tells you which of the 12 zodiac signs the Moon was in, while the phase tells you where it was in its waxing/waning cycle relative to the Sun.
