Why does my whole generation have Neptune in the same sign?

Neptune spends about fourteen years in a sign, so a whole span of births shares it. Astrology reads Neptune by sign as what a cohort idealized and blurred, a description of a generation, and keeps those entries short. The house is where it becomes personal.

What does Neptune rule?

Pisces, in the modern scheme; Jupiter ruled Pisces before Neptune was found in 1846 and is still read as its older ruler. Neptune's natural house is the 12th: solitude, what is given without credit, what a person keeps from themselves.

Is Neptune retrograde at birth significant?

Not much. Neptune is retrograde about five months of every year, so almost half of everyone has it. Astrologers read it, if at all, as a slight turning inward of the blur. The house and the aspects to personal planets carry the reading.

Neptune in astrology: the slow planet of ideals and blur

Neptune is the eighth planet and the farthest, an ice giant a little smaller than Uranus, found in 1846 after its pull on Uranus had been worked out on paper. One trip around the Sun takes about 165 years, fourteen years or so in a sign, and no one lives to see it come back. In a chart it carries what a cohort idealized and blurred.

What it is: The eighth planet, an ice giant, found in 1846
Zodiac cycle: About 165 years, about fourteen years per sign
Retrograde habit: Around five months each year
Sign ruled: Pisces
Natural house: The 12th
Its domain: What a cohort idealized and blurred

Fourteen years to a sign

Neptune's orbit takes about 165 years, so it covers roughly two degrees a year and spends about fourteen years in one sign. Nobody has watched it go around once since its discovery; it completed its first observed orbit in 2011, and no one who saw the start saw the finish. A planet that takes two lifetimes to come around cannot say much about one life by sign: a sign is a fourteen-year stretch of births, and what it describes is the stretch. Its yearly backward spell runs about five months and is read lightly.

What a cohort idealized and blurred

The thing a generation held up as the ideal, and the edges it let go soft: that is what a Neptune sign records, and the site's entry for it is two or three sentences that name the generation. Neptune in Scorpio, from about the mid 1950s to 1970, is a cohort that idealized intensity and blurred what was private; Neptune in Capricorn, from the mid 1980s to 1998, a cohort that idealized the career and blurred where work stopped.

The house is still one person's

Two people born the same year share a Neptune sign and need not share its house: a few hours of clock time move it several houses along, and that house is where the blur sits in one life, so the entry for it runs full length. A Neptune in the 2nd does not know what is in the account and is right that it is about enough; a Neptune in the 7th falls for who the partner could be and keeps the photograph from the first year on the fridge; a Neptune in the 10th has a job title nobody at the party can repeat back and is fine with that.

A transit of a year or more

Neptune belongs with Jupiter, Saturn, Uranus and Pluto in the slow transit reading. A moving Neptune in aspect to a natal body is in orb for a year or two and exact up to five times as the loops cross and recross the degree; Neptune takes about fourteen years to cross one house. Over a stretch that long the reading cannot name an event, so it names what has gone soft at the edges, and what the person is doing about it this month. Neptune squares its own natal place near forty-one, the one Neptune transit everyone of an age meets together.
