Why the week count moves the way it does

Weeks are the unit people actually plan in. Deadlines, notice periods and rotas run in weeks, which is why a week count tends to be more useful than a raw day count once you are more than a fortnight out. Note that the two figures answer slightly different questions: "how many weeks" is full weeks only, while "weeks and days" keeps the remainder.

About Black Moon August 2027

August 31, 2027 at 17:42 UTC brings a second new moon in a single calendar month — a Black Moon, the new moon's answer to the Blue. It happens only every two to three years, which is exactly why the phrase 'once in a blue moon' means what it means.

This one peaks at 8°06' Virgo. Nothing looks different from an ordinary full or new moon — the rarity is purely calendrical, and the counter above treats it like any other: with perfect accuracy.
