One day before the archer's year
By the end of November the Sun has covered about 29 of Scorpio's 30 degrees, and the northern nights are long. The step to Sagittarius at 240 degrees is the one that moves the zodiac from fixed water to mutable fire, from the sign that holds to the sign that roams.
November 21 is observed as World Television Day by the United Nations, set by a 1996 resolution, and World Hello Day, begun in 1973 to encourage people to greet ten others. The first comes from a debate about media and the second from an effort at peace-making, and neither has anything to do with the Sun's position.
Is November 21 a cusp date?
A birthday at the very end of Scorpio, a fixed water sign, is read in tradition as the sign at full depth but already inclined to look outward. The overlap with Sagittarius is the one named the Cusp of Revolution in popular astrology. If your birth falls after the crossing in your time zone, the Sagittarius reading is the one to follow.
The standard table gives Scorpio. The change from Scorpio into Sagittarius can reach November 21 in some year and time zone within 2000 to 2050, so a birth on this date can belong to either sign.
Across 2000 to 2050 (51 years) the Sun entered Sagittarius on these UTC dates: November 22 in 35, November 21 in 16.
Within those years the entry into Sagittarius fell on November 21 between 15:30 and 23:40 UTC; on November 22 between 00:10 and 17:40 UTC. Clocks in populated time zones run from UTC-10 to UTC+12, so the same instant can read as the day before or the day after, and your birth time and birth place decide which side of it you were born.

The Scorpio decan for November 21
November 21 falls in decan 3 of Scorpio, November 12 to 21, ruled by Cancer. Each sign is cut into three decans of about ten days, ruled in turn by the sign itself and the next two signs of its element.
Cancer, another water sign, rules the third Scorpio decan, and the stretch is traditionally tied to feeling and memory more than to Scorpio's usual intensity. Of the three decans of the sign it is the softest, which makes it a useful companion to the sign's reputation rather than a contradiction of it.
Birthday number 3 for November 21
The day 21 reduces to 3: 2 + 1 = 3. No step lands on a master number.
A 21 reduces to 3 (2 + 1), and the decan here is the third as well, which is a coincidence between two unrelated systems rather than a link. Numerology reads 3 as expression and sociability, so a 21 birthday is described as talkative and warm, a counterweight to the reserve written about Scorpio.
The November birthstone
Birthstones follow the month and not the day, so a birthday on November 21 shares Topaz (also Citrine) with every other November birthday. See November birthstones.
November 21 zodiac questions
Could a November 21 birth be Sagittarius?
Yes. The calendar gives Scorpio, but in years when the Sun crossed into Sagittarius on November 21 in UTC, a birth after that moment is Sagittarius, and the table here prints how often that happened.
What decan governs November 21?
It falls in the third Scorpio decan, ruled by Cancer, based on the dates used on the month page. Decans are an older refinement, and sources differ on the exact days.
How does November 21 differ from November 22?
On the calendar the 21st is the last full day of Scorpio and the 22nd the first day of Sagittarius, a change from fixed water to mutable fire. Since the Sun's crossing can fall on either date, the clock decides.
