‘This Is Us’: What Year Were the Big Three Born?

The timelines in NBC’s This Is Us are almost turning into scientific equations lately on figuring when certain events happened.

For those who have good memories or abilities to calculate those timelines, it’s fun when the show jumps back and forth through the decades in a puzzle piece fashion to connect events. Others may find it a little too confusing to the point where it’s never really known how old the Big Three are.

If going by the “present” on TIU, one has to assume the current time (2019) is the main timeline. All other time variances are mostly flashbacks to the 1970s and ’80s, then occasional flash-forwards to 12 years into the future and even 25 years later.

With all of this, what year exactly were the Pearson kids born? Calculating this isn’t quite as hard as one would think.

One clue is that the kids are young teenagers by the time of Jack’s death

Based on the overall timeline, it’s said that Jack Pearson died in 1998, which would make the Big Three around 17 or 18 at the time. Maybe some would argue the kids don’t look this age when the death scene occurs, bringing more confusion on how old they were supposed to be then.

Not that determining age can always be determined by what kids look like. Sometimes kids look older when younger and vice versa. Using the same teen actors for this period between the early ’90s to 1998 likely perplexed viewers trying to piece the timelines together.

Maybe trying to determine the Big Three ages in the ’90s wasn’t the best idea. If going by their ages in the current timeline of 2019 (or even their proposed ages in the future), it’s possible to pinpoint an exact year of their birth.

Many viewers might have assumed the Pearson Three birth year was more the late 1970s based on the date of when Rebecca and Jack married. Based on some simple math, the births occurred at the dawn of the 1980s.

Apparently Jack and Rebecca waited a while to have kids

There still isn’t an exact established year when Jack and Rebecca married. While viewers have seen flashbacks to their wedding, there isn’t an agreed upon time on when it was supposed to happen.

Based on the timeline, it was at some point between 1972 and 1980. Most assume it was around 1976 based on the clothing and hairstyles.

This wedding scene takes place at a City Hall, but most media analysts who’ve created This Is Us timelines still haven’t pinpointed an exact date. Perhaps future episodes will finally give a set year, even if one can assume Rebecca and Jack had at least a 20-year marriage if not more.

Rebecca getting pregnant didn’t happen until the night of the Super Bowl in 1980, aka January 20. It’s a little surprising Jack and Rebecca waited a few years to have kids, besides maybe holding off due to financial reasons.

After all, when it was found out they’d be having triplets, Jack had to confront his estranged father about borrowing money to buy a house for his upcoming new family.

Are the Pearson kids really almost 40 now?

At least it’s been confirmed August 31, 1980 is when the Big Three were born. In August of 2020, all three of the Pearson kids will turn 40.

Does this really line up with the real ages of the actors? Going by biographical data, the ages of each actor are fairly close in real life. Justin Hartley will be 43 in 2020. Sterling K. Brown is also 43 as of this year. Chrissy Metz, on the other hand, is the closest to the age of Kate in the show thanks to being born on September 29, 1980.

With the Pearson kids being 40 in 2020, they’ll likely experience a lot of new life obstacles. No doubt most of those are part of the journey everyone will be seeing as lead-up to the inevitable conclusion of everyone gathering by Rebecca’s deathbed, somewhere in the indefinite future.
