Mycroft Holmes: zodiac sign and birth chart
Mycroft Holmes has no canon birthday. Conan Doyle never gives one. Read from his personality, he is an Aries. Aries Sun, Moon, rising and Mercury: a chart that decides fast and expects to be obeyed. He is Sherlock's older brother, even smarter and far too lazy for legwork.

NEBO's take
No birthday in canon. His personality says Aries.
We ran Mycroft through the same model that matches people to characters in the app, and looked at which chart gets him most often. It reads him as fire: decisive, commanding and used to getting his way.
Canon

CanonNot in canonNEBO's takeAries
Aries decides and moves. A call from Mycroft opens doors, archives and borders ordinary people never see.
- Moon
CanonNot in canonNEBO's takeAries
An Aries Moon is impatient. He sits at the Diogenes Club, where talking is forbidden, because most conversation is a waste of time.
- Rising
CanonNo birth timeNEBO's takeAries
No birth time in canon. First impression: an umbrella, a three-piece suit and a look that has already filed you.
- Mercury
CanonNot in canonNEBO's takeAries
Aries Mercury is short and direct. He says what he wants in one sentence.
- Venus
CanonNot in canonNEBO's takePisces
Pisces Venus hides the soft part. In the BBC series his care hides behind sarcasm and control.
- Mars
CanonNot in canonNEBO's takeLibra
Libra Mars pulls strings instead of fighting. He gets what he wants through offices, not violence.
What canon does give: a brother with a mind even sharper than Sherlock's, who prefers his armchair and now and then practically runs the country. Aries is the command, Libra Mars the quiet pull on strings.
How he shows up
Why he's like this
Aries is the sign of command, speed and being first to decide. Mycroft hits it in scenes fans know.

Occasionally the government
Holmes says that his brother holds a minor post but is the most indispensable man in the country, and occasionally is the British government.

FeelingsAries Moon
The Diogenes Club
He is a member of a club where talking is forbidden, and it suits him perfectly.

Leaves his rut
When national secrets are stolen, Mycroft comes to Baker Street in person, which Holmes says he almost never does.
