Does the timing of a haircut or nail-cutting matter?

This is one of the most traditional and culturally widespread timing beliefs. Almanac specifies days that are inauspicious for cutting hair or nails — particularly the 1st and 15th of the lunar month, and days that clash with specific elements. The belief is rooted in the idea that hair and nails are extensions of the body's vital energy (氣), and cutting them on inauspicious days can drain that energy. Jyotish has a parallel tradition: cutting hair on certain days of the week is considered inauspicious (Tuesday and Saturday are traditionally avoided in many Hindu traditions). Islamic Astrology recommends cutting nails on Fridays as a Sunnah practice. While these traditions may seem minor, they reflect a broader principle: small daily choices, made with cosmic awareness, accumulate into a life lived in alignment.
