Laundry by the moon
Laundry by the lunar calendar: the next favorable day is Sunday 6 September. Score calendar, goals and the traditional rules behind every date.
Why by the moon?
Laundry belongs to the waning moon in tradition: dirt and stains are said to release more easily, and the wash comes out thoroughly clean with less detergent (Paungger/Poppe). The same logic applies to almost all household cleaning.
Whether water-sign days help on top is disputed — the link to the water element is intuitive, but not all traditions know the rule. It therefore counts at half weight.

When should you do laundry according to the lunar calendar?
According to Paungger/Poppe, laundry gets most thoroughly clean during a waning moon — dirt is said to release from the fibres more easily then.
Do water-sign days help with laundry?
The traditions disagree: parts of folk tradition consider days with the moon in Cancer, Scorpio or Pisces especially good washing days, while other accounts contradict this. According to Paungger/Poppe, the waning moon matters more.
