[Minerva McGonagall] is born[JKR] said in [Sch2] that [McGonagall] was "a sprightly 70" years old. Using that information, we can determine the year in which she was born by subtracting 70 years. As with [Dumbledore]'s birthyear, the trick, of course, is knowing what year to subtract that 70 years from. If we assume that Rowling was saying that [McGonagall] was 70 years old at that point in the stories, which was summer of 1995 [[Y15]], then she was born in [Y-55] ([Y15] minus 70 years). According to the official timeline, [Y-55] is 1925. Interestingly, that would make [McGonagall] a contemporary of [Tom Marvolo Riddle] at [Hogwarts]...

(BFT)

[Bob Ogden] visits the [Gaunt house] on a routine follow-upThere he encounters the irate [Marvolo Gaunt] who, along with his son [Morfin], refuse to admit [Morfin] has done anything wrong. When [Bob Ogden] steps in to stop them injuring Morfin's sister, [Merope], he is driven from the house. He returns later with reinforcements, and [Marvolo] and [Morfin] are each sent to [Azkaban].

This happens "a few months" before [Merope] marries Tom Riddle.

(HBP10)

[Merope Gaunt] fools Tom Riddle into marrying herShe most likely does so by giving him a [love potion].

[Dumbledore] says that [Merope] and Riddle were married about a year before [Tom Marvolo Riddle] was born, on December 31, 1926 [[Y-54]].

(HBP10)

[Marvolo Gaunt] returns from [Azkaban] to find [Merope] goneHe had been given a six-month sentence. Forced to live alone, he withers away and dies sometime within the next two and a half years.

(HBP10)

[Merope Gaunt] gets pregnant with [Tom Marvolo Riddle]Her husband, [Tom Riddle], leaves her very soon afterward - [Dumbledore] suspects because she stops giving him [love potion].

The date is deduced from being nine months before [Voldemort]'s birth date. We know Riddle leaves her soon afterward because they were only married for "a few months."

(HBP10)

[Merope Gaunt] sells [Slytherin's locket] to [Borgin and Burkes]Pregnant and desperate for money, she has no idea what it's worth and is only given ten [Galleons] for it. The [locket] is later sold to [Hepzibah Smith].

According to [Caractacus Burke], this happened "just before Christmas."

(HBP13)

[Tom Marvolo Riddle] is bornHe is born in a Muggle [orphanage] to a witch mother, [Merope Gaunt], and Muggle father, [Tom Riddle]. His mother [Merope] dies an hour later, living just long enough to name her son after his father, Tom, and her father, [Marvolo Gaunt] ([HBP13]). She is nineteen years old.

The older [Tom Riddle] had previously left [Merope] when he realized that she was a witch ([HBP10]), and the child is raised in the [orphanage] ([HBP13]).

[Tom Marvolo Riddle] said that he was sixteen years old at the time of [Hagrid]'s expulsion from [Hogwarts] ([CS17]). [Hagrid] was expelled in his third year, which was fifty years ago from June of 1993 [[Y13]]. Tom was therefore 16 in 1943 [[Y-37]] - meaning his sixteenth birthday was New Year's Eve, 1942 [[Y-38]], and his date of birth was in 1926 [[Y-54]]. However, according to the official timeline ([CS/DVD]), [Hagrid]'s expulsion was in June of 1942, not 1943, which means that [Hagrid]'s expulsion from Hogwarts was actually fifty-ONE years before June of 1993 [[Y13]]. Riddle was 16, then, in June of 1942 [[Y-38]], and therefore was born in 1925 [[Y-55]]. Either date may be considered correct. However, since the Lexicon follows what is directly given in the books over other sources, the dates in this timeline are derived from a literal interpretation of fifty years.

New Year's Eve is given in [HBP13]. Depending on exactly when [Merope Gaunt] arrived at the orphanage, Tom may have been born on New Year's Eve or just after midnight, on New Year's Day. Since the book says New Year's Eve, however, that's what we go with here.

The 1940s

Events of this decade:

[Albus Dumbledore] is the [Transfiguration] teacher at [Hogwarts][Armando Dippet] is the Headmaster.

We don't know exactly when [Dumbledore] took the [Transfiguration] post (except that it was before 1938 [[Y-42]]), but we do know that he taught [Transfiguration] while [Tom Marvolo Riddle] was a student ([HBP13], [HBP20]).

[Frank Bryce] returns from fighting in World War Two.He "had a hard war," according to the barkeep at the pub in [Little Hangleton]. He was wounded and walks with a limp. He takes up as gardener for the Riddles and avoids people for the most part.

[Bryce] came home quite a few years before the end of the war in 1945, undoubtedly because he was wounded.

(GF1)

1940 (Y-40) AD = 59 MM = 15 TR = 14 RH = 12

[Rubeus Hagrid] starts his first year at [Hogwarts] and is sorted into [Gryffindor]His birthday is December 6 ([JKR]), so he turns 12 a couple of months after starting [Hogwarts].

Meanwhile, [Tom Riddle] is starting his third year, and [Minerva McGonagall] her fourth.

The year is based on [Hagrid]'s birthdate of December 6, 1928 [[Y-52]].

c. 1941 (Y-39)

This happened somewhere between [Hagrid] starting at [Hogwarts] in the fall of 1940, and his expulsion in the spring of 1943.

(CS)

All we know is that [Hagrid]'s father died during his second year, so it's equally possible that his death was in fall of 1941 or spring of 1942.

[Tom Riddle] learns to open the [Chamber of Secrets] and releases the [Basilisk]"It had taken me five whole years to find out everything I could about the Chamber of Secrets and discover the secret entrance."

(CS17)

[Myrtle], a [Hogwarts] student, dies in a second floor bathroom after seeing the [Basilisk] (CS16)

[Hagrid] is falsely accused of opening the [Chamber of Secrets]He is so accused because [Tom Riddle] catches him raising an [Acromantula] in the castle.

(CS17)

[Aragog] the [Acromantula] is released into the [Forbidden Forest] ([CS13])[Hagrid] will later find him a wife, [Mosag], and together they will establish a colony ([CS15]).

[Rubeus Hagrid] is expelled from [Hogwarts]He is expelled after being accused of opening the [Chamber of Secrets].

(CS17)

[Tom Riddle] is given an [Award for Special Services to the School]He receives it for helping "catch" [Hagrid] and accusing him (falsely) of opening the [Chamber of Secrets] ([CS13], [CS17]).

[Hagrid] remains at [Hogwarts] and is trained as gamekeeper, thanks to [Dumbledore]"Only the Transfiguration teacher, [Dumbledore], seemed to think [Hagrid] was innocent. He persuaded Dippet to keep [Hagrid] and train him as gamekeeper."

(CS17)

[Tom Riddle] commits his first murders: his father and grandparents in their [Little Hangleton] mansionHe first visits his uncle, [Morfin Gaunt], and uses magic to steal [Marvolo]'s ring and frame [Morfin] for the murders of the Muggles in the [Riddle house].

The next day, [Morfin] is taken to [Azkaban], where he remains until his death.

"In the summer of his sixteenth year, he left the [orphanage] to which he returned annually and set off to find his [Gaunt relatives]... Meanwhile, in the village of [Little Hangleton], a maid was running along the high street, screaming that there were three bodies lying in the drawing room of the big house: [Tom Riddle] Senior and his mother and father."

(HBP17)

[Tom Riddle] meets with [Professor Slughorn] and asks him about [Horcruxes]He is now wearing the ring he stole from his uncle [Morfin] during the summer, and is accompanied by his group of friends which includes [Avery] and [Lestrange].

(HBP23)

[Tom Marvolo Riddle] creates his first [Horcrux]: the [diary]He uses the recent murders and the knowledge he gained from [Slughorn] to work the Dark Magic required to turn the diary into a [Horcrux] ([HBP23]).

"I knew it wouldn't be safe to open the Chamber again while I was still at school. But I wasn't going to waste those long years I'd spent searching for it. I decided to leave behind a diary, preserving my sixteen-year-old self in its pages, so that one day, with luck, I would be able to lead another in my footsteps, and finish [Salazar Slytherin]'s noble work" ([CS17]).

Tom says that he placed his "sixteen-year-old self" into the diary ([CS17]), so he must have done it in the fall after the summer when he killed the Riddles and before he turned 17 at the end of December. His conversation with [Slughorn] where he learned about [Horcruxes] must have taken place after school started that September, so the timeframe for the creation of the diary Horcrux is between September and December, 1943 [[Y-37]]. All along, Tom realized that [Dumbledore] was watching him closely ([HBP23]).

1944 (Y-36) AD = 63 MM = 19 TR = 18 RH = 16

[Tom Riddle] begins his seventh year at [Hogwarts] and is made [Head Boy]He is dabbling in the [Dark Arts], having already created a [Horcrux], and some of his closest friends are already referring to him as Lord [Voldemort]; outwardly, however, he is a model student ([CS17], [HBP23]).

1945 (Y-35) AD = 64 MM = 20 TR = 19 RH = 17

[Tom Riddle] graduates and applies for a job teaching at [Hogwarts]Headmaster [Armando Dippet] turns him down, saying that at eighteen he is too young. He then goes to work for [Borgin and Burkes] instead.

We don't know when this happened exactly, except that it was almost certainly within a few weeks of the end of school. [Riddle] gets the job at [Borgin and Burkes] "the next thing the staff knew," according to [Dumbledore].

(HBP20)

World War Two ends

c. 1947 (Y-33)

We don't know exactly when this happened, but it is probably within a couple of years of [Voldemort]'s leaving [Hogwarts]. It's possible this happened later than 1946 or 1947 [[Y-34] or [Y-33]], but unlikely that it happened sooner.

The 1950s

Events of this decade:

All this time, [Tom Riddle] was becoming the evil Dark Lord [Voldemort], consorting with the worst of Wizardkind and learning secrets and dark magic that would change him forever from the handsome, talented boy of the 1940s into a twisted, horrible person who would be known as the most evil wizard of his age. One can only imagine that [Dumbledore] kept watch for all those years, waiting and wondering what happened to the boy he knew as [Tom Riddle]...

1951 (Y-29) AD = 70 MM = 26 TR = 25 RH = 23

This was written in November of 1994 [[Y14]], which would make [Rita]'s birth year 1951 [[Y-29]] on the official time line ([CS/DVD]). Of course, [Rita] could very well have been lying about her age...

"Thirty-nine years this December," said [Professor McGonagall] brusquely, snapping her bag shut."

She started teaching 39 years before the December of 1995 [[Y15]], so it was 1956 [[Y-24]] on the official timeline ([CS/DVD]).

(OP15)

c. 1957 (Y-23)

Again we don't know exactly when this happened, but since most evidence points to [Dumbledore] becoming headmaster in 1956 [[Y-24]], [Voldemort] couldn't have come looking for a job much sooner than this.

(HBP20)

1957 (Y-23) AD = 76 MM = 32 TR = 31 RH = 29

So he was born 38 years before 1995 [[Y15]]. This corresponds to 1957 [[Y-23]] on the official timeline. That means he's my age... ([SVA])
