Dalton Trumbo’s zodiac sign and chart, in brief
9 December 1905 was a Saturday: the day Dalton Trumbo was born in Montrose, Colorado. That made Dalton a Sagittarius, with the Moon in Taurus. Dalton died on 10 September 1976, aged 70. No verified birth time is on file for Dalton; the chart is cast for midday, without houses.
Of the nine planets whose sign does not depend on the birth time, three are in earth signs, three in air, two in fire and one in water. By modality the count is four fixed, three mutable and two cardinal. No two planets sit closer to an exact angle than Sun and Mars: a sextile, about 0.7° from exact at midday. Aspects to the Moon are not counted, because the Moon moves about thirteen degrees in a day. Mercury, Jupiter, Neptune and Pluto were retrograde. The Moon was waxing gibbous, between first quarter and full.
StarMap's dataset holds 17 other people born on 9 December, among them Kirk Douglas, Judi Dench and John Malkovich.

Dalton Trumbo’s Sun, Moon and rising sign
Sun sign
Sagittarius
about 17° Sagittarius at midday
A Sagittarius Sun seeks. Meaning, distance and the bigger picture are likely to pull Dalton Trumbo forward, and the honesty of this placement is a kind of generosity. Its lesson is that the journey also needs somewhere to land.
Moon sign
Taurus
in this sign all day; the degree depends on the birth time
A Taurus Moon feels through the body and its surroundings. On this reading, good food, familiar places and slow evenings are what restore Dalton, and sudden change lands hard. Once they feel safe, they can be the steadiest person in the room.
Rising sign
The rising sign changes about every two hours, so it cannot be known without a birth time. The table below shows which sign was rising over Montrose, Colorado, at each hour of the day.
Dalton Trumbo’s rising sign, by birth time
StarMap has not verified a birth time for Dalton yet. It shows a birth time only when Astro-Databank rates it AA, A or B on the Rodden scale (AA from a birth certificate or record, A from the person, someone close to them or a news report, B from a biography). Until then, this is the rising sign for every possible time of birth on 9 December 1905, computed for Montrose, Colorado.

Dalton Trumbo’s planets, sign by sign
Each planet by sign: what the placement is traditionally taken to mean, not a claim about Dalton Trumbo’s private life.
Growth, travel and ideas bigger than daily life are where Dalton Trumbo's Sagittarius Sun finds purpose, and their energy tends to lift the moment there is somewhere new to go. Familiarity is what wears on this placement. A few months into any routine, however good it is, restlessness usually sets in.
A Taurus Moon needs routine, familiar food and physical comfort to feel steady from day to day. A sudden change of schedule probably unsettles Dalton more than they let on. A good bed, a favourite mug or the same coffee order can turn an unsteady morning around.
Mercury in Capricorn or Sagittarius
Capricorn until about 17:55, then Sagittarius
mind and voice
Born before about 17:55: Mercury in Capricorn
Mercury in Capricorn thinks methodically, and Dalton tends to communicate in a measured, practical way that people trust. The focus on a useful conclusion can be so strong that ideas which have not yet proven their worth are dismissed. Dalton will often get straight to the point in a conversation other people expected to be casual.
Born after about 17:55: Mercury in Sagittarius
Dalton's Mercury in Sagittarius thinks in big, connective leaps and communicates with enthusiasm and a wide frame of reference drawn from everywhere they have been. The weak point is generalising past what the details support. A specific question may get a sweeping theory nobody quite asked for.
Venus in Sagittarius loves with enthusiasm and a need for shared adventure, and Dalton probably values a partner who gives them room to roam. When things get serious, this placement can confuse freedom with distance. The pattern with this Venus is to plan the next trip together before settling into the current one.
Mars in Aquarius acts on principle, and its anger surfaces most over unfairness or hypocrisy rather than personal slights. Dalton can detach from a conflict so thoroughly that the other person feels shut out. The issue tends to get argued with heat while the relationship itself is treated with strange calm.
Jupiter in Taurus
29° Taurus 23' at midday ℞
growth and excess
In Dalton's chart, Jupiter in Taurus grows through patience, and what it builds tends to come together slowly and steadily rather than in one leap. Taken too far, that can become excess: holding on to more comfort or more stuff than serves them. They are probably generous with food, gifts and shared pleasures, and now and then generosity tips into indulgence.
With Saturn in Aquarius, Dalton's discipline probably gathers around belonging to a group on their own terms; it is the placement of the one-time outsider. The doubt means holding back the stranger ideas until there is no risk of mockery. The outsider often ends up as a trusted voice in exactly the kind of community that once seemed unlikely to accept them.
Uranus in Capricorn
3° Capricorn 21' at midday
freedom, generational
Many people within a few years of Dalton's age share Uranus in Capricorn, the mark of a generation that dismantles and rebuilds old institutions and structures of authority. Personally, that can mean scepticism towards any system that asks for trust without having shown why it deserves it.
Neptune in Cancer
9° Cancer 36' at midday ℞
imagination, generational
Neptune in Cancer is shared by Dalton and many people born in the same decade or so. The generation idealises home and family, often carrying a wider nostalgia for a version of belonging that may never quite have existed. Personally it can be a soft-focus longing for a childhood home.
Pluto in Gemini
21° Gemini 49' at midday ℞
power, generational
Dalton shares Pluto in Gemini with many people born in the same long stretch of years. That generation transforms communication and collective thought, often through upheavals in how information is controlled and shared. The personal portion is an intense relationship with what counts as truth.
Aspects in Dalton Trumbo’s chart
How the planets stand to each other, tightest first. Without a birth time the orbs are those at midday, and aspects to the Moon are left out because the Moon moves about thirteen degrees in a day.
Sun sextile Mars
about 0.7° at midday
Dalton Trumbo's identity and energy work together, giving them an easy confidence that is there when they decide to use it. With this aspect, taking the initiative comes more naturally than might be expected, especially when the stakes are theirs to own.
Venus opposition Jupiter
about 1.7° at midday
With Venus opposite Jupiter, Dalton's own taste can pull against other people's grander expectations of romance or generosity, and the temptation is to overextend to meet them. Trusting a private sense of what is enough works better than matching someone else's scale.
Jupiter square Saturn
about 1.9° at midday
Enthusiasm for growth can run into limits here, whether practical or self-imposed, and to Dalton it may feel as though ambition keeps outrunning the time and energy available. Jupiter square Saturn works best when the limit is treated as a pace-setter and not as a wall.
Mercury sextile Saturn
about 2.7° at midday
Turning a loose idea into something solid is easier with Mercury sextile Saturn, because Dalton's thinking and sense of structure work together. The clarity is quiet and practical, and it shows most when a plan has to work.
Mercury conjunction Uranus
about 3.2° at midday
Dalton's thinking is likely to be quick, original and a step ahead of convention, with insights that arrive suddenly rather than through slow reasoning. Mercury conjunct Uranus makes for inventive thinking, and the courtesy worth learning is explaining the leap so that other people can follow it too.
Venus square Saturn
about 3.6° at midday
Venus square Saturn can pair the desire for closeness with a fear of not being quite enough to keep it. For Dalton that may mean self-doubt in relationships that have given no reason for it, and the fear can ease each time they let themselves be loved without first having to deserve it.
The rest, listed without a reading. Those between Uranus, Neptune and Pluto hold for years at a time, so everyone born while one holds shares it.

How this page is made
Planet positions are computed with the astronomy-engine ephemeris and checked against Swiss Ephemeris. Birth dates and places come from Wikidata; birth times, where StarMap has one, come from Astro-Databank and are shown with their Rodden rating. The readings describe what a placement is traditionally taken to mean. They are written by StarMap for reflection and entertainment, not as statements about the person’s private life. New to charts?
