Sagittarius dates
The Sun enters Sagittarius at 240° of ecliptic longitude and leaves at 270°, the December solstice. For a US Eastern birth the start fell on 22 November in 60 of the 80 years from 1951 to 2030 and on 21 November in 20. Those 21 November starts are a recent habit. The 1950s had none and the 1960s had none; the first came in the 1970s, and the decade counts climb from there:
| Decade | Years Sagittarius began on 21 November (US Eastern) |
|---|---|
| 1950s | 0 of 10 |
| 1960s | 0 of 10 |
| 1970s | 1 of 10 |
| 1980s | 3 of 10 |
| 1990s | 2 of 10 |
| 2000s | 4 of 10 |
| 2010s | 4 of 10 |
| 2020s | 6 of 10 |
The end date is firmer. Capricorn began on 21 December in 57 of the 80 years and in all 10 of the years 2021 to 2030, US Eastern time, and the last 22 December end on the East Coast came in the 2010s. London is still split down the middle, 40 years on the 21st and 40 on the 22nd, and Sydney, eleven hours ahead of London in December, mostly sees the change on 22 December (69 years).
Ophiuchus, the 13th sign, and why Sagittarius dates stay put
Every few years a headline announces that the zodiac has changed and that people born in late November and early December are really Ophiuchus, the Serpent-bearer. The best-known rounds came in January 2011, after a Minneapolis newspaper quoted a local astronomer on the drift of the constellations, and in September 2016, when a NASA page for children that explained the same drift was shared as "NASA changed your star sign". NASA's own reply was that it had changed nothing; it had done the maths about the constellations. Both stories were right about the sky and wrong about astrology.
Here is what the sky actually did in 2026, using the International Astronomical Union's constellation boundaries. Tropical Sagittarius ran from 22 November 2026 at 07:23 UTC to 21 December 2026 at 20:50 UTC. The Sun spent the first day and a half of it among the stars of Libra, reached Scorpius on 23 November, crossed into Ophiuchus at about 06:00 UTC on 30 November, and only reached the constellation Sagittarius at about 14:00 UTC on 18 December. Of the 29.55 days of the sign, roughly eighteen had the Sun in Ophiuchus and only about three in the archer's own stars. 2027 is nearly identical, with Ophiuchus from 30 November to 18 December.
| Constellation (IAU) | Sun enters, 2027 | Until |
|---|---|---|
| Sagittarius | 1 Jan | 20 Jan |
| Capricornus | 20 Jan, about 09:00 UTC | 16 Feb |
| Aquarius | 16 Feb, about 19:00 UTC | 12 Mar |
| Pisces | 12 Mar, about 21:00 UTC | 19 Apr |
| Aries | 19 Apr, about 09:00 UTC | 14 May |
| Taurus | 14 May, about 20:00 UTC | 22 Jun |
| Gemini | 22 Jun, about 04:00 UTC | 21 Jul |
| Cancer | 21 Jul, about 09:00 UTC | 11 Aug |
| Leo | 11 Aug, about 08:00 UTC | 17 Sep |
| Virgo | 17 Sep, about 09:00 UTC | 31 Oct |
| Libra | 31 Oct, about 21:00 UTC | 24 Nov |
| Scorpius | 24 Nov, about 00:00 UTC | 30 Nov |
| Ophiuchus | 30 Nov, about 12:00 UTC | 18 Dec |
| Sagittarius | 18 Dec, about 20:00 UTC | 31 Dec |
Look at the whole table and the "13 signs" idea falls apart on its own terms. The constellations are not equal. Virgo holds the Sun for more than six weeks and Scorpius for under one, because the IAU drew its boundaries in 1930 along lines of right ascension and declination, to divide the whole sky into 88 tidy regions for star maps. Astrology played no part in where the lines went. A zodiac built from them would have thirteen unequal segments that shift slowly with precession.
The tropical zodiac was never built from them. Its twelve signs are equal 30° sections of the ecliptic, counted from the March equinox, and they describe the year's seasons. Ophiuchus was well known to the astronomers who used the signs: it is one of the 48 constellations in Ptolemy's star catalogue, and the Sun's path crossing its feet was no secret. They kept twelve signs anyway, because the signs were never meant to be the star figures. So a Sagittarius born on 5 December is a Sagittarius in the tropical system now, as in the 1950s, whatever the IAU boundary says about the stars behind the Sun that day.
What the headlines do show is real: the constellations have slipped by almost a full sign against the seasons since the classical period. Sidereal astrology follows that slip and gives later dates. Western tropical astrology, which this site uses, does not, and that is a choice of definition rather than a mistake about astronomy.

Why Sagittarius is one of the shortest signs
The Sun stays in Sagittarius for 29.55 days on average, between 29.55 and 29.56 across 1951 to 2030. Only Capricorn, at 29.44, is shorter; Aquarius, at 29.59, comes a whisker behind. Cancer, at the other end of the year, takes 31.45 days, almost two days longer.
The cause is Earth's orbit, which is slightly elliptical. Earth is closest to the Sun in the first days of January and moving fastest then, so the Sun's apparent motion through the signs either side of the new year is quicker. Sagittarius sits just before that closest point, Capricorn across it. The 30° are the same; the days needed to cross them are not.
| Sign | Average days, 1951 to 2030 | Shortest to longest |
|---|---|---|
| Cancer | 31.45 | 31.45 to 31.46 |
| Gemini | 31.33 | 31.32 to 31.34 |
| Leo | 31.29 | 31.29 to 31.30 |
| Taurus | 30.97 | 30.95 to 30.98 |
| Virgo | 30.90 | 30.89 to 30.91 |
| Aries | 30.46 | 30.45 to 30.48 |
| Libra | 30.39 | 30.37 to 30.40 |
| Pisces | 29.96 | 29.95 to 29.97 |
| Scorpio | 29.90 | 29.88 to 29.91 |
| Aquarius | 29.59 | 29.58 to 29.60 |
| Sagittarius | 29.55 | 29.55 to 29.56 |
| Capricorn | 29.44 | 29.44 to 29.45 |
A short sign holds fewer births, and Sagittarius holds fewer still than its length explains. The Shymea rarity study counted 4,945,436 Sagittarians among 62,187,026 US births from 2000 to 2014, 7.95%, the tenth of the twelve signs by size. On days alone the share would be 8.09%; the 2014 figure was 7.86%, a ratio of 0.971. One likely reason is the holidays. US births dip noticeably around Thanksgiving and Christmas, when fewer inductions and planned caesareans are booked, and both fall inside or beside Sagittarius.
Elsewhere it is rarer still. Sagittarius was twelfth of twelve in Canada in 2024 at 7.67%, the least common sign there, and eleventh in England and Wales in 2025 (7.83%) and in Australia in 2023 (7.64%, eleventh). New York City in 2024 put it tenth, at 8.09%.
| Registry | Sagittarius share | Rank (1 = most common) |
|---|---|---|
| United States, 2000 to 2014 (62,187,026 births) | 7.95% | tenth of 12 |
| England & Wales, 2025 | 7.83% | eleventh of 12 |
| Canada, 2024 | 7.67% | twelfth of 12 |
| Australia, 2023 | 7.64% | eleventh of 12 |
| New York City, 2024 | 8.09% | tenth of 12 |
Sagittarius date by year, 1980 to 2030
Each row gives the instant the Sun entered Sagittarius in four places, and the instant it left in two. A birth between the two instants, in your own zone, is a Sagittarius. The November start shifts about six hours later each year and jumps back after a leap day, so the earliest starts are in leap years such as 2028, when the Sun arrives at 1:54 pm on 21 November in New York.

Born on 21 or 22 November, or 21 or 22 December?
From 23 November to 20 December every birthday was Sagittarius in each year 1951 to 2030 in all four US zones, and from 24 November in the UK. The six edge days are below; for any of them, the zodiac sign calculator takes your date, birth time and town and gives the answer for that year.
| Birthday | US Eastern | US Pacific | UK | Sydney |
|---|---|---|---|---|
| 21 November | Scorpio all day 60; changed during the day 20 | Scorpio all day 49; changed during the day 31 | Scorpio all day 73; changed during the day 7 | Scorpio every year |
| 22 November | changed during the day 60; Sagittarius all day 20 | changed during the day 49; Sagittarius all day 31 | changed during the day 68; Sagittarius all day 7; Scorpio all day 5 | changed during the day 48; Scorpio all day 32 |
| 23 November | Sagittarius every year | Sagittarius every year | Sagittarius all day 75; changed during the day 5 | Sagittarius all day 48; changed during the day 32 |
| 21 December | changed during the day 57; Sagittarius all day 23 | changed during the day 65; Sagittarius all day 15 | Sagittarius all day 40; changed during the day 40 | Sagittarius all day 73; changed during the day 7 |
| 22 December | Capricorn all day 57; changed during the day 23 | Capricorn all day 65; changed during the day 15 | changed during the day 40; Capricorn all day 40 | changed during the day 69; Capricorn all day 7; Sagittarius all day 4 |
| 23 December | Capricorn every year | Capricorn every year | Capricorn every year | Capricorn all day 76; changed during the day 4 |
22 November is the usual handover in US Eastern time, a change-over day in 60 of the 80 years and Sagittarius from midnight in another 20. 21 November was Scorpio all day in 60 years, but on the West Coast it was a change-over day in 31, so a Californian born on the 21st has a real chance of being a Sagittarius; the calculator settles which. The Scorpio dates, ending 21 or 22 November page covers that edge from the Scorpio side, and November zodiac signs lists the month day by day.
At the solstice end, 21 December was a change-over day in 57 years in US Eastern time and wholly Sagittarius in only 23, so a 21 December birthday needs the hour, and the sign calculator has every year's time. The Capricorn dates from the 21 December solstice and December zodiac signs pages pick up from there. A cusp birth belongs to one sign or the other. The tradition has no blended sign, only a Sun early or late in a sign.
Sagittarius generations: Pluto, Neptune and Uranus
Three outer planets passed through Sagittarius within living memory, and between them they cover most people born from 1970 to 2007. The Sagittarians among them carry the sign twice. Dates are DE442 ingresses in UTC.

| Uranus | 17 Feb 1981 to 20 Mar 1981; 16 Nov 1981 to 15 Feb 1988; 27 May 1988 to 2 Dec 1988 | 1981 to 1987; 22 Nov to 2 Dec 1988 |
| Neptune | 4 Jan 1970 to 3 May 1970; 6 Nov 1970 to 19 Jan 1984; 23 Jun 1984 to 21 Nov 1984 | 1970 to 1983 |
| Pluto | 17 Jan 1995 to 21 Apr 1995; 10 Nov 1995 to 26 Jan 2008; 14 Jun 2008 to 27 Nov 2008 | 1995 to 2007; 21 Nov to 27 Nov 2008 |
Pluto's stay, 10 November 1995 to 26 January 2008, covers a large share of Generation Z: every Sagittarius born from 1995 to 2007 has Pluto in Sagittarius too. Neptune was there from 6 November 1970 to 19 January 1984, and Uranus joined it on 16 November 1981, so the Sagittarians of 1981 to 1983 have both outer planets in their sign.
1983 went further. Jupiter, the sign's ruler, was in Sagittarius from 26 December 1982 to 19 January 1984, so a Sagittarius born in late 1983 has the Sun, Jupiter, Uranus and Neptune in one sign, a stellium that the stellium guide reads through the house it falls in. The 1985 to 1987 group has Saturn with Uranus instead.
Jupiter's sign: Sagittarius in the tradition
In Tetrabiblos I.17 Jupiter, "moderate and below Saturn's sphere", receives the two signs next to Saturn's: Sagittarius and Pisces, which Ptolemy calls "windy and fecund". They stand in triangular aspect to the houses of the luminaries, Sagittarius trine to Leo and Pisces to Cancer, "a harmonious and beneficent configuration". Sagittarius is the masculine of Jupiter's two houses.
Ptolemy's term for the sign's type is bicorporeal (I.11), meaning two-bodied. It is usually tied to the centaur, half man and half horse, but his own reason is the weather. The bicorporeal signs follow the solid ones and "share, as it were, at end and beginning, the natural properties of the two states of weather": Sagittarius is the last month of autumn running into winter. The modern word is mutable.
Sagittarius belongs to the fire triangle with Aries and Leo, which I.18 gives to the Sun by day and Jupiter by night, with Sagittarius lying "to the winter solstice". In Ptolemy's list of exaltations (I.19) no planet is exalted in Sagittarius and none falls there. By the traditional rule Mercury, ruler of Gemini opposite, is in detriment, which is the classical way of saying that this sign prefers the large view to the exact detail.
Sagittarius in a job, a marriage and an ordinary week
Jupiter in a mutable fire sign looks like range. The Sagittarius at work is often the one who explains things: the teacher, the trainer, the colleague who turns a dull policy into a story people remember, and who has already booked the conference abroad. Mercury in detriment shows in the follow-through. The big picture is right and the expense form is wrong.
In a marriage the classic Sagittarius trait is candour that arrives before tact. Asked whether the new sofa works, they will tell you, and then suggest a holiday instead. An ordinary week tends to have a plan for something further off than next week: a course, a trip, a move.
What Sagittarius does not mean: it does not make anyone flaky, commitment-shy or permanently on a plane. Many Sagittarians stay in one job and one town for decades and do their travelling in books. A Sagittarius Sun with a Virgo Moon and Capricorn rising is careful with money and slow to move, and only the birth chart shows that. Check your rising sign before you trust the Sun-sign description.

Sagittarius in 2027
The Sun enters Sagittarius on 22 November 2027 at 13:16 UTC, 8:16 am Eastern on 22 November, and reaches the solstice and Capricorn on 22 December at 02:42 UTC. Mars gets there first, entering on 15 October (UTC), followed by Venus on 1 November and Mercury on 29 November, so the sign is already busy when the Sun arrives.
The Sagittarius New Moon is on 28 November at 5°39′, which is 10:24 pm EST on 27 November. Earlier, the Full Moon in Sagittarius on 19 June at 27°33′ falls on the Sun degree of people born around 19 December. Jupiter, the ruler, spends the first seven months in Leo, a fire sign trine to Sagittarius, before it moves into Virgo on 26 July and makes a square instead. The Sagittarius 2027 horoscope has the year in full, and the Sagittarius horoscope the current week.
| Date (UTC) | Event | Degree | US Eastern time |
|---|---|---|---|
| 7 Jan | Venus enters Sagittarius | 0°00′ | Jan 7, 3:53 am EST |
| 19 Jun | Full Moon in Sagittarius | 27°33′ | Jun 18, 8:44 pm EDT |
| 15 Oct | Mars enters Sagittarius | 0°00′ | Oct 15, 7:14 pm EDT |
| 1 Nov | Venus enters Sagittarius | 0°00′ | Nov 1, 3:35 am EDT |
| 22 Nov | Sun enters Sagittarius | 0°00′ | Nov 22, 8:16 am EST |
| 28 Nov | New Moon in Sagittarius | 5°39′ | Nov 27, 10:24 pm EST |
| 29 Nov | Mercury enters Sagittarius | 0°00′ | Nov 29, 5:24 am EST |
The decans of Sagittarius
Three ten-degree slices, each roughly ten days long, shifting by a day with the year like the sign.
| Decan | Degrees | Usual dates (UTC) | Chaldean face ruler | Triplicity sign (modern scheme) |
|---|---|---|---|---|
| First | 0° to 10° | 22 November to 1 December | Mercury | Sagittarius |
| Second | 10° to 20° | 2 December to 11 December | the Moon | Aries |
| Third | 20° to 30° | 12 December to 21 December | Saturn | Leo |
In the older system of faces the first decan belongs to Mercury, the planet in detriment in this sign, then the Moon, then Saturn. The modern scheme gives Sagittarius, Aries and Leo, which reads as Jupiter, Mars and the Sun. The third decan, roughly 12 to 21 December, is the one that differs most between the two: Saturn's face on the doorstep of Capricorn in one scheme, the Sun's warmth in the other.
Sagittarius compatibility
Gemini is the opposite sign and the mirror of rulers: Mercury at home there and in detriment here, Jupiter at home here and in detriment there. Gemini and Sagittarius is two talkers, one about facts and one about meaning. Aries and Leo share the fire triangle a trine away (Aries and Sagittarius, Leo and Sagittarius). Pisces shares Jupiter as ruler but sits square, so Sagittarius and Pisces has a common outlook and different habits.
Scorpio and Capricorn are the neighbours and, 30° apart, in aversion by the old rule. Scorpio and Sagittarius is a pairing people search for often; the Sun signs only open the question, and synastry compares the whole charts. All twelve signs and their dates are on the zodiac signs by date page.
