1881 or 1882
Dumbledore is born.
Dumbledore is forty-five in 1927, which would mean he’s either born in 1881 or 1882. Simply subtracting his age from the year gives 1882, but if his birthday is still yet to come at that time, it may be 1881.
SCENE 27 EXT. DOME OF ST. PAUL’S—EVENING
Apparating beside a dandyesque forty-five-year-old wizard with graying auburn hair and beard. NEWT hands back his glove.
NEWT
Dumbledore.
- Fantastic Beasts: The Crimes of Grindelwald (The Original Screenplay)
1896 or 1897
Leta Lestrange and Newt Scamander are born
Leta and Newt are in the same year at Hogwarts since they take class together, and are both thirteen in 1910 (seventeen years before 1917), so they’d have to be born in 1896 or 1897 depending if their birthdays had already passed.
SCENE 68 INT. HOGWARTS CUPBOARD—SEVENTEEN YEARS PREVIOUSLY—MORNING
13-YEAR-OLD LETA slams the door and stands there, ear against it. She hears running, distant shouts. Then a sound behind her makes her jump and turn around.
13-YEAR-OLD NEWT is already in occupation of the cupboard. He has hidden a couple of tanks here, one containing tadpoles, another Streelers.

1901
Corvus Lestrange Jr. is born.
Corvus Jr.’s birth year is explicitly stated as being 1901 in the Fantastic Beasts: The Crimes of Grindelwald screenplay.
SCENE 103 INT. LESTRANGE MANOR, BEDROOM—1901—DAY
We reenter the story to find LESTRANGE SR. with a new, blond wife.
KAMA (V.O.)
He remarried not three months after her death. He loved her no more than he had loved you . . . But then . . .
IRMA takes the BABY BOY who has just been born, and passes him to LESTRANGE SR., who is delighted.
KAMA (V.O.)
. . . his son, Corvus, was born at last. And that man who had never known love was filled with it . . .
- Fantastic Beasts: The Crimes of Grindelwald (The Original Screenplay)
Credence Barebone is (likely) born.
Credence was likely born in 1901, since he looked similar enough to Corvus Jr. for neither Irma nor his aunt to notice they had a different baby than the one they got on the ship with.
The ship lurches again. IRMA snatches BABY CREDENCE, not noticing the switch amid the confusion.
- Fantastic Beasts: The Crimes of Grindelwald (The Original Screenplay)
Irma, Leta, and Corvus Jr. go to America, Corvus Jr. drowns.
The screenplay explicitly states that Irma, Leta, and Corvus Jr. take the trip to America, and Corvus Jr. is stated to drown in that year as well.
SCENE 109 EXT. LIFEBOAT—1901—NIGHT
CHILD LETA, IRMA, and BABY CREDENCE are in one boat, CREDENCE’S AUNT and BABY CORVUS in another.
Around 1908
Newt and Leta start at Hogwarts.
Since Newt and Leta were in the same year at Hogwarts, and were both thirteen in 1910, and the age that students start at Hogwarts, they’d likely have started attending Hogwarts in 1908.
Around 1915
Newt and Leta would graduate from Hogwarts.
Since Newt and Leta likely had their first year at Hogwarts in 1908, they’d graduate seven years later in 1915.
1927
Grindelwald is supposed to be tried for his crimes in Europe.
The screenplay of Fantastic Beasts: The Crimes of Grindelwald says that Grindelwald was going to be transported to Europe to be charged there.
SPIELMAN
Six months are enough. It’s time for him to answer for his crimes in Europe.
- Fantastic Beasts: The Crimes of Grindelwald (The Original Screenplay)
Grindelwald escapes from MACUSA custody.
Also stated in the screenplay as being 1927, Grindelwald escapes from the carriage used to transport him.
Still driving the carriage, GRINDELWALD swirls his wand in the air toward the surrounding storm clouds. One by one, forks of lightning strike the broomstick riders, knocking each in turn from the sky.
Around 1927
Tom Riddle was born.
Fifty years from the events of Chamber of Secrets, Tom Riddle was sixteen years old, and since those events occurred in around 1993, he’d likely have been born around 1927 - which would accord with his birth date in the books being December 31st, 1926.
TOM RIDDLE
I knew it wouldn't be safe to open the Chamber again while I was still at school. So I decided to leave behind a diary, preserving my sixteen-year-old self in its pages, so that one day... I would be able to lead another to finish Salazar Slytherin's noble work.
- Harry Potter and the Chamber of Secrets (Script)
Around 1943
The Chamber of Secrets was opened.
One year before the events of the Prisoner of Azkaban, the Chamber of Secrets was said to be opened fifty years ago, placing its opening in around 1943.
DRACO
You know I haven't, Goyle. How many times do I have to tell you? But my father did say this much: It's been fifty years since the Chamber was opened. He wouldn't tell me who opened it -- only that they were expelled -- but I know this: the last time the Chamber of Secrets was opened, a Mudblood died.
- Harry Potter and the Chamber of Secrets (Script)
Moaning Myrtle was killed by the basilisk.
Also fifty years ago from the events of Chamber of Secrets, Moaning Myrtle was killed by the basilisk.
HARRY
Remember what Aragog said? About that girl fifty years ago? She died in a bathroom. What if she never left.
RON
Moaning Myrtle!
- Harry Potter and the Chamber of Secrets (Script)
1981
Harry’s parents are killed.
The script for Harry Potter and the Deathly Hallows Part 1 shows that Harry’s parents’ tombstones say they died in 1981.
Around 1981 - 1982
Sirius Black is convicted and sentenced to Azkaban.
The Potters died in 1981, and from when Arthur Weasley said it was thirteen years ago since the Potters died, Sirius Black says he spent twelve years in Azkaban.
SIRIUS BLACK
I did my waiting! Twelve years of it! In Azkaban! Trust me, you wouldn't have lasted a week!
- Harry Potter and the Prisoner of Azkaban (Script)
Peter Pettigrew goes to live with the Weasleys.
Pettigrew also went to live as a rat in the Weasley house twelve years ago from when Arthur Weasley said was thirteen years after the Potters died.
RON
Scabbers? Scabbers has been in my
family for --
SIRIUS BLACK
(bitterly)
Twelve years. A curiously long life for a common garden rat.
- Harry Potter and the Prisoner of Azkaban (Script)
1991
Harry turns 11, finds out he’s a wizard, and starts at Hogwarts.
Ten years after Harry is left on the Dursleys’ doorstep because his parents died, he turned eleven.
Almost ten years after: The Dursleys’ home. The camera pans on a sleeping boy, almost eleven, with a lightning-bolt shaped scar on his forehead.
- Harry Potter and the Sorcerer’s Stone (Script)
1992
Harry starts his second year at Hogwarts.
Since Harry’s parents died in 1981, and Harry turns eleven ten years after that, we can see his first year at Hogwarts would have been in 1991,
1993
Harry is a third year at Hogwarts.
Harry’s parents died on the same day that Harry ‘stopped’ the Dark Lord, which is mentioned in Harry Potter and the Prisoner of Azkaban as being thirteen years ago, which would mean that it’d be around 1994 when Arthur said that presuming he was being precise, but since Harry would be turning thirteen and his parents died when he was about one, it should be around twelve years instead.
ARTHUR WEASLEY
Harry, thirteen years ago, when you stopped...
Mr. Weasley hesitates, unable to continue.
HARRY:
Voldemort...?
- Harry Potter and the Prisoner of Azkaban (Script)
1994
Harry is a fourth year at Hogwarts.
1995
Harry is a fifth year at Hogwarts.
1996
Harry is a sixth year at Hogwarts.
1997
Harry drops out of Hogwarts to hunt Horcruxes.
