What is Paksha (Lunar Fortnight)?
Shukla Paksha (bright fortnight) runs from New Moon to Full Moon, while Krishna Paksha (dark fortnight) runs from Full Moon to New Moon. The Moon is considered naturally stronger during Shukla Paksha, gaining Paksha Bala (fortnight strength) in Shadbala calculations. Birth during Shukla Paksha is generally considered more auspicious, particularly near the Full Moon. The Tithi (lunar day) within each Paksha further refines timing. The 8th Tithi (Ashtami) and 14th Tithi (Chaturdashi) of both Pakshas are considered challenging.
