Understanding moon phases and daily guidance

Waxing moon

From new moon to full moon the moon is associated with growth. Planting, building practices, plans and undertakings with a growth character fit this phase well.

Waning moon

From full moon to new moon the moon supports letting go, cleansing and completion. Tidying up, decluttering, stabilising hairstyles or running reductions fits now.

Full moon & new moon

On these days the energy is at its peak (full moon) or turned inward (new moon). Many lunar calendars avoid major interventions, operations or busy schedules during these windows.

Critical lunar days

Lunar days 9, 15, 19, 23 and 29 are treated as sensitive in central-European tradition. On the homepage they are marked as “unfavourable” — also check the moon sign for finer guidance.

FAQ

How is the moon phase computed?

From the ecliptic-longitude difference between Sun and Moon. The page shows the phase, moon sign and lunar-day index using the same logic as the calendar.

Why are the homepage days often neutral?

The general moon calendar only evaluates the basics: phase, motion and critical lunar days. Topic-specific guidance (haircut, dentist, garden) lives in the dedicated sections — those evaluations are sharper.

Can I rely on the moon calendar alone?

No. The calendar is planning orientation — professional advice and real-life context always take priority.
