I've changed Severus' birth year from 1960 to 1959 according
to new information I compiled. This is a huge puzzle for everyone so I've been compiling
ALL possible information pertaining to Snape's birthday. It should reveal
the birth year of Lupin and James for sure. I've gone where
no one has before, apparently, so it may change lots of dates in the end
because the HP Lexicon always said the most probable date was 1960.
However, after analysing all the facts we were presented (canon
and official only), I've made many calculations and ended up changing
the year of events from 1959 up to 1980 when Harry was born.
Facts from all 6 books
- The real problem is knowing in what year they all began!
If we had this, it would be easy to extrapolate the necessary
information. But we don't. Here is what we have however:
- Students can only enter Hogwarts if they are at least 11years
old on Sept. 1st. Even if you were born in
September like Hermione or on Sept. 2nd, you could not
- Hogwarts 5th Year students must be at least 15 years old
when they come to school on Sept. 1st
- Therefore, Snape's birthday being in January, he was
11 and 7 months when he got into Hogwarts.
OWLs are in 5th Year. In the first two weeks of June.

Snape and Lupin were at least 16 when they sat their OWLs.
The Marauders, Lily and Snape were all in the same year.
Only Lupin and Snape have specific birthdays.
Hogwarts students who started in
1970 were born in-between Sept.2nd 1958 and Sept. 1st 1959.
Students who started in 1971 were born in-between Sept.2nd
1959 and Sept. 1st 1960.
James still being 15 near the end
of his 5th Year proves he had to be born in the exact same year
as Snape and Lupin or else he would have been almost 16 or would
have entered Hogwarts a year later. It
is a correlation: if Snape was born in 1959, so was Lupin and
James. If Snape was born in 1960, so were Lupin and James.
Sirius could also follow the same pattern (see
Rowling mentioned on her site that Lupin
and Sirius are the same age but have different maturity.
So their birthdays must not be so far apart (Spring or early
(Snape's Worst Memory ) Snape was described as being
fifteen or sixteen, around Harry's own age. It makes sense because
he was 16 and 5months.
James was fifteen at that moment but Harry was able to tell
right away without hesitation. So maybe Snape looked a bit older.
If so, and because of Hogwarts rules, then James's
birthday must be sometime during the summer because he was still
15 while sitting his OWLs! He is younger than Severus but born
the same year.
Sirius said of James that "of course he was a bit of
an idiot" and "we all were idiots". This
suggests that they were maybe close in age as well. Since Lupin
was born in March, we can assume Sirius comes next and/or around
the same time as James in summer.
Release of Goblet of Fire in March: J.K. Rowling said Snape
is about 35 - 6.
Goblet of Fire happened from school year Sept. 1994
to June 1995
- She could mean that he was 35 or 36 at the beginning
of the book, at the end of it or all through that school
- But since she said "is" and not "was",
we can assume she referred to the end of the book as in
"up to now in the series, Snape's 35 - 6" OR
the whole book as in "In Goblet of Fire, Snape is 35
Rowling mentioned on her site that Sirius was about
22 when he was sent directly to jail after being refused
a trial on November 1st, 1981. So
'about' may mean 21, 22, 22 and a couple of months, or 23. However, since she said 22 and
not 21 or 22/22 or 23, we can assume 22 is
the best age and that the "about" meant that he had
22 and a couple of months... (See
my calculations here)
Snape was hired on Sept. 1st 1981. Umbridge inspects his
classroom on October 7th 1995 and
mentions he's been teaching for 14 years.
This is in accordance with the fatidic night of Nov. 1st

- Conclusions -
- that when Rowling said
Snape 'is' 35 - 6 after publishing Goblet of Fire,
she most probably meant it as in "up to this date
in the series"
Then Snape was most likely born in 1959 OR 1960.
Then Snape would have become a teacher at Hogwarts at 22 or
However, considering ....
- that Sirius was about
22 (and some months) on Nov. 1st 1981 (see
- that Lupin was the same
age as Sirius
- that Lupin was born only
two months after Snape (making those three close in age)
- that Lupin and Snape were
also X-years and some months old
- that they were all in
the same school year
- that you need to be 16
in your 6th Year and 17 in your 7th at Hogwarts
Then Snape was most
likely born in 1959.

He entered Hogwarts in 1970 and graduated in June 1977.
Three years later, Harry Potter was born in late July 1980.

more if he joined (after he was of age in January 76).
I've used the astrological sign attributed to January 9th
because I believe that Rowling may be someone who would purposely
look up such "muggle magic" before making a choice. I
must say that, though I've seen somewhere that most people believed
he was a Scorpio, that this sign suits him very well. See
this website here that I found while looking up information
on Capricorns yesterday, and you'll know what I mean. (It's a good
site I reckon since there was no advertising on it! Which is quite
The VS shaped symbol or sometimes written like this '6 over the
Internet is the sign of Capricorns which is why I used it for this
wallpaper. I think it suits Snape very well, too.
I took the round Capricornus icon on this
webpage where the whole set is featured. Please visit!
I also found this funny picture of a Capricorn which might have
inspired Rowling to decide upon Snape's birthday... What do you
think? ; ) Coincidence?!
