The Moon is in Pisces, near its first quarter, climbing toward full.

What does the Sun or Moon in Pisces mean?

Pisces is a mutable water sign ruled by Jupiter in the classical scheme, and it reads as the part of anyone that dissolves the edges between things.

The Sun spends about a month here at the end of winter, roughly mid February into the March equinox. A Pisces Moon lasts about two and a half days and often reads as porous: more imaginative, more tired, more affected by other people's moods than usual.

Mutable means it takes the shape of what surrounds it, and water means it works by feeling. That makes for real empathy and real art, and the cost is that boundaries blur when you are not watching. Deciding where yours are is the useful move here.

Pisces is the last stretch of the tropical zodiac, ending at the March equinox where Aries begins again, which is why it reads like the end of a cycle.
