Friday the 13th Part 4-6 Timeline Placement (Tommy Jarvis Trilogy)

As I stated before in my Jason Voorhees Canonical Age there has always been a "somewhat" conflicting timeline for F13: The Final Chapter til F13: Jason Lives itself! here is how this can all be translated into the official canon without the usage of any actual "headcanon" and "Theories" from the fans BUT with actual evidence from both the films and official material!! The alternative title for this article is Tommy Jarvis Age.


Tommy Jarvis is 12 years old during the time of Friday the 13th: The Final Chapter meaning Tommy was born in the year of 1972 this all adds up since Friday the 13th Part's 2-4 all take within the same year of the same month and weekend that yeat being 1984 and how do we know that? 

Evidence 1: Pamela's Grave stone literally states a given year that she died in 1979 and see the evidence 2 section for the year of 1984 being the year of Part 4!!

Evidence 2: Alice was stalked and killed 5-years prior to the events of Friday the 13th Part 2 quick math for everyone to understand that 1979+5=1984 the year Part 2 takes place! Let's re-visit the camp fire story told by Paul Holt himself. 

Paul Holt wrote:She claimed she saw him. She disappeared two months later.

Alice Hardy was killed in Mid-August 1979 and Paul went on to state this as well:

Paul Holt wrote:Five years... five long years he's been dormant...

Now that we established this for those who are curious about the mathematics of how we got these numbers for the Part 4 time placement since it started June 13, 1984 and the massarce ended a week (or weekends?) time and no we don't know the exact time span of how long Jason was out during Part 4 Morgue situation, I'll get into that time placement later!!


Tommy Jarvis is said to be about 17 years old for this installment....so let's do the math!

1984 Tommy is 12 years old
1985 Tommy is 13 years old
1986 Tommy is 14 years old
1987 Tommy is 15 years old
1988 Tommy is 16 years old
1989 Tommy is 17 years old
1990 Tommy is 18 years old

So we can confirm now that Friday the 13th Part V A New Beginning takes place in the year 1989! so we have our official year for this film's own in-universe timeline! this matches with my Jason Voorhees Canonical Age post as well for this 5-years time skip!

To add more evidence a fellow F13 Fan his name is Joshua D. King also posted this on a Friday the 13th fan group!!


So now we got an Official Month stitched into Friday the 13th a New Beginning timeline discussion which its either Early or Mid October of 1989 as source material help add this to discussion to help solve more details for us!!


Tommy Jarvis is now 18 years old in 1990 as a year after the events of Part V, so logically due to the decay process of Jason Voorhees when Tommy digs him up from his grave! And let me beg you are wondering how aren't ya?

And so a BIG thank you to Friday the 13th Franchise website for finding this section of the Friday the 13th Part VI: Jason Lives Script of it outright stating Tommy Jarvis was 18-years old!!!


The Link to their Original Article: Original Friday the 13th Part 6 Script

So this is from the source material itself and helps further cites my statements here!!!! 

Decomopositation Stages!

This should be noted to all the readers!! This is discussion will also be based on the climate, environment, and overall exposure to nature! so yes we are using science to explain this section as well and not "Supernatural" excuses!

If Jason Voorhees himself was truly left to rot without anyone actually caring to even bury him then Jason's entire body would have been complete bones by exceeding 45+ days alone from nature quickly taking it over if they never buried him BUT here's for information!!

Backed Up Evidence?!

Australian Museum wrote:Although an exposed human body in optimum conditions can be reduced to bone in 10 days, a body that is buried 1.2 m under the ground retains most of its tissue for a year.

Jason obviously wasn't buried at 1.2m as evident in Jason Lives he was atleast buried 3.2m. 

More scientific evidence???

Live Science wrote:Although the process of decomposition starts within minutes of death, there are a number of variables, including the ambient temperature, soil acidity and coffin materials, which can affect how long it takes a body to skeletonize. However, on average, a body buried within a typical coffin usually starts to break down within a year, but takes up to a decade to fully decompose, leaving only the skeleton

Live Science wrote:A body buried without a coffin, which doesn't have protection from insects and other elements, typically skeletonizes within five years

Scientifically speaking yet again, Jason was buried in New Jersey, and as someone who lived in New Jersey I can state the temperature in Summer is Warm and Humid as the Winters are absolutely colder than mkst states!! Thus the decomposition of Jason's Corpse is severally different depending on the severity of the seasons. 

Even more statements!!!

Poe wrote:If the body was not embalmed or if the embalming process was not effective, after 6 months, the body may have undergone significant decomposition, resulting in skeletal remains

Now IF a corpse is/was left in a well-maintained coffin where the body is properly prepped and embalmed it will help explain his new clothes being so similar to when he was alive and why we don't see the machete marks on his back clothing! (Again this is debunking the concept that "Continuity is bad in Friday the 13th!") With a coffin blocking out the more natural process it would take a minimum of 10 years to be skeletonized! BUT since we clearly saw dead small animals, the maggots, and cobwebs on Jason's Corpse this picture is for evidence to help solidify this explanation!!


So not only was his coffin barely maintained it was still exposed to insects! this is why he looks the way he does after 6-long years of being a corpse! this is what they called advanced decay/mummification stages! so it all logically makes sense for the timelines 


Friday the 13th Part 4 takes in place 1984
Friday the 13th Part 5 takes in place 1989
Friday the 13th Part 6 takes in place 1990

All these Evidence was given from and by the source material, math, and science! I hope you all enjoyed this reading!


For alternatives for these timelines? These could also still exist in terms of the age of Tommy Jarvis!

1984 Tommy is 12 turning 13 years old
1985 Tommy is 13 turning 14 years old
1986 Tommy is 14 turning 15 years old
1987 Tommy is 15 turning 16 years old
1988 Tommy is 16 turning 17years old
1989 Tommy is 17 turning 18 years old
1990 Tommy is 18 turning 19 years old

These alternates wouldn't be incorrect due to the fact

We don't have a canon birthday (MM/DD/YY) for Tommy Jarvis and can only figure this out based on the math solutions for the year of his birth only not the Month/Day.

under short summary you have part 5 twice f.y.i.
