The 12th Lunar Day in the Tibetan Calendar

The 12th lunar day is a waxing-moon day (day 12 of the bright fortnight). In zurkhai, the lunar day is one of the main inputs used to decide whether a given date is favourable for an undertaking such as travel, a business opening or a medical treatment.

Cutting hair on the 12th lunar day

Tibetan-Mongolian almanacs assign every lunar day a specific result for cutting hair. The 12th day is traditionally said to lead "to danger to life" — unfavourable for a haircut. (The first day of life, by contrast, and several waning days are avoided.) The Zurkhai app shows this haircut reading for every day of the year, so you never have to count lunar days by hand.

Across the lunar month, virtue is concentrated on the holy days — the 8th (Medicine Buddha), 10th (Guru Rinpoche), 15th (full moon), 25th (dakini) and 30th (new moon) — when the fruits of action are traditionally said to multiply. The 12th day leads up toward the full moon, the high point of the bright fortnight.
