The best and most auspicious days to cut your hair in January 2040 are 1, 2, 3, 4, 5, 6, 7, 13, 21, 22, 23, 30 and 31, with 1, 2, 3, 4, 5, 30 and 31 the most favourable of all (Moon in Leo or Virgo). Avoid cutting on 14, 17, 18, 26, 27, 28 and 29 (New Moon — 14 January · Full Moon — 29 January). These readings follow European lunar folk tradition — the Moon’s phase and zodiac sign.
What to do when
Under a waxing Moon — tradition says hair regrows faster after a cut.
Under a waning Moon — the cut lasts longer and regrowth slows.
The favourable signs (Leo, Virgo, Taurus, Capricorn, Libra) are also the traditional colouring days.
Under a waning Moon — the traditional time for masks, nourishing and root care.

Frequently asked questions
Which are the best and most auspicious days to cut hair in January 2040?
The favourable haircut days in January 2040 are 1, 2, 3, 4, 5, 6, 7, 13, 21, 22, 23, 30 and 31. Tradition's best are 1, 2, 3, 4, 5, 30 and 31 — the days with the Moon in Leo or Virgo.
Is this a Feng Shui or panchang auspicious-date calendar?
No. These dates come from European lunar folk tradition: the Moon's phase (waxing or waning) combined with the zodiac sign it stands in. It does not use the Chinese almanac, Ghost Month, or the Vedic panchang, so its "auspicious" days will not always match a Feng Shui or Hindu calendar. The astronomy behind it — phase and sign for any given day — is computed and verifiable; the meaning attached to it is tradition, not science.
When should I cut my hair for faster growth in January?
Tradition says hair regrows faster when cut under a waxing Moon — in January 2040 that falls on 15, 16, 19, 20, 21, 22, 23, 24 and 25.
Which days are unsuitable for a haircut in January 2040?
Tradition does not cut on 14, 17, 18, 26, 27, 28 and 29 — the new and full moon days (New Moon — 14 January · Full Moon — 29 January) and the days with the Moon in Cancer or Pisces (folk belief: thinning and dandruff).
When should I colour my hair in January 2040?
Tradition assigns colouring to the days with the Moon in a favourable sign (Leo, Virgo, Taurus, Capricorn, Libra) — in January 2040 those are 1, 2, 3, 4, 5, 6, 7, 13, 21, 22, 23, 30 and 31.
How does a lunar haircut calendar work?
Two rules combine. Under a waxing Moon (new → full) tradition cuts for faster regrowth; under a waning Moon, to keep the shape and strengthen the roots. The zodiac sign sets the verdict: Leo and Virgo are best, Taurus, Capricorn and Libra favourable, Cancer and Pisces unfavourable, the rest neutral. The new and full moon are rest days.
Is there scientific evidence?
No. The moon phase and its zodiac sign are astronomically computed and verifiable, but their link to hair growth is folk belief. This page reproduces the rules of the popular lunar almanacs as entertainment — it is not advice.
