Best haircut days, month by month
A calendar-first answer to "when should I cut my hair?" Each month is scored day by day across seven calendar traditions, weighted for the lunar hair-care folklore — the almanac's 理发 days and the waxing-moon windows.

How to use this page
Lunar hair care is the most-kept timing folk practice in the world: trim on the waxing moon for growth, on the waning moon to keep a cut longer. This page ranks each month's days by the traditions that watch hair — the almanac's own 理发 register and the moon's phase — and adds your clash sign.
The clash rule (冲煞) — yes, even for haircuts
Almanac practice checks the day's clash against the recipient's birth-year sign even for 理发 appointments, on the logic that any deliberate change to the body deserves a day that does not clash its owner. Pick your sign above; clashing days drop out.
What the score already weighs
The haircut read weights the almanac's 理发 days and the moon's phase hardest — waxing moons classically favor growth, waning moons favor keeping a shape — with lighter weights on the remaining traditions.
Honest boundary
There is no scientific evidence that moon phase affects how hair grows. The practice survives because it gives the routine a rhythm. Book the appointment that fits your schedule; let the calendar break the tie.
Frequently asked questions
Does cutting hair during a waxing moon make it grow faster?
It is long-standing folk practice — the waxing moon is read as a growth window — but there is no scientific evidence that moon phase affects hair growth. Treat it as ritual rhythm, not biology.
Why do some months list mostly one phase?
The waxing-window days cluster around the new-to-full half of each lunar cycle, so favorable haircut days bunch together. A month dominated by waning days is the calendar telling you to schedule the next cut, not this one.
Should my stylist's sign matter?
Folk practice checks the person undergoing the change, not the hands performing it. One sign to check per appointment.
Is the almanac's 理发 entry the same as the moon rule?
No — they are independent layers. The almanac lists 理发 as a suitable activity on specific days; the moon phase is a separate folk layer. This page ranks days where both agree, which is why some convenient Saturdays do not make the list.
