The New Moon, First Quarter, Full Moon, and Third Quarter are moments in time,

with no duration.

The Waxing and Waning Crescents, and the Waxing and Waning Gibbous phases,

each last roughly a week.

You might well argue that each day is a different "phase". But we generally think of four separate "phases of the Moon", each of six days, with sharp one-day divisions between them.

New Moon

Waxing Crescent

First Quarter

Waxing Gibbous

Full Moon

Waning Gibbous

Third Quarter

Waning Crescent

We probably don't see the 3rd Quarter or Waning Crescent, because they are visible between midnight and dawn.

The waxing crescent, waxing gibbous, waning gibbous, and waning crescent
each last roughly a week. (Nominally 7.38 days)

The New Moon, First Quarter, Full Moon and Third Quarter are technically single
moments in time, that mark the beginning or end of the 7-day phases.

My closest answer is 3.5 days but I'm not exactly sure.
