When we are children, a summer vacation feels endless. Waiting for your birthday feels like waiting for a century. December seems impossibly far away from January.
Then adulthood happens. 😶
Suddenly, January is becoming December before you've properly understood what happened. You just blink, and another year is gone. You check the calendar and think, “Wait... wasn't it just New Year?”
Apparently, time did not actually speed up.
We did.
When Did the Years Become So Short?
Ask a five-year-old how long one year is, and it probably feels enormous. Ask someone who has lived for fifty years, and that same year can feel like it disappeared somewhere between Monday morning and Sunday evening.
The clock, of course, doesn't care about any of this. A minute is still a minute. An hour is still an hour. The Earth continues doing its thing with impressive consistency.
So why does time feel faster as we grow older?
One important explanation is that our perception of time is closely connected to novelty, attention, and memory. When we are young, much of life is new. Our first day at school, first bicycle ride, first trip, first friendship, first love, first festival, first big embarrassment—we experience countless things for the first time.
Our brains have a lot to remember.
As adults, however, life often becomes more predictable. Wake up. Work. Eat. Check the phone. Work again. Scroll a little longer than intended. Sleep. Repeat.
And suddenly it's Friday. 🤡
Again.
The Firsts Make Time Feel Longer
Think about your first trip to a completely new place. You probably remember many details: the streets, the smells, the food, the people, the strange little things that happened along the way.
Now compare that with an ordinary Tuesday.
You probably remember... Tuesday.
That's the strange relationship between memory and time. Periods filled with new and distinctive experiences tend to leave more memories behind. When we look back, those periods can feel longer and richer.
Routine does the opposite.
When many days look almost identical, the brain doesn't need to create a separate mental folder for every one of them. Ten ordinary days can blur together into what feels like a single memory.
This is one reason childhood can feel so long in retrospect.
There were simply more “firsts.”
The Mathematics of Growing Older
There is another interesting way to think about this. That our brain doesn't literally calculate the percentage every time December arrives. But psychologically, each additional year can represent a smaller fraction of your accumulated experience.
A year that once felt enormous gradually becomes one small chapter in a much larger book.
And the book keeps getting thicker.
The Routine Trap
Modern life makes the problem even more interesting.
As we grow older, responsibilities increase. School becomes college. College becomes work. Work becomes deadlines. Deadlines become emails. Emails become more emails.
Our days become structured around efficiency.
We take the same route, eat similar meals, visit familiar places, follow familiar routines, and consume the same types of content.
Convenience is wonderful.
But too much predictability can make time feel like it is disappearing.
The brain loves patterns. Unfortunately, it isn't particularly interested in giving every repetitive Tuesday its own documentary.
Why Vacations Feel Longer
Have you ever noticed that the first few days of a vacation can feel surprisingly long?
You're in a new place. Everything is unfamiliar. You're paying attention to details you normally ignore. The road looks different. The food tastes different. Even figuring out where to find a decent cup of tea becomes an adventure.
Then you return home. 🥲
Three days later, you have no idea where the weekend went.
The difference isn't necessarily the number of hours.
It's the number of experiences packed into those hours.
This is why deliberately creating new experiences can make life feel richer—not because it literally gives us more time, but because it gives our memories more to hold onto.
Maybe We Don't Need More Time
This leads to an uncomfortable thought.
Perhaps our biggest problem isn't that life is getting shorter.
Perhaps we are simply becoming less present inside it.
We can spend an entire meal thinking about tomorrow, an entire weekend worrying about Monday, and an entire vacation documenting it for people who weren't there.
We can be physically present somewhere while mentally being three notifications away.
And then we wonder where the day went.
Time was there.
We just weren't fully there with it.
Make Some Days Difficult to Forget
Maybe the answer isn't to constantly chase excitement. Nobody needs to turn every Tuesday into an extreme sport.
It is simply about creating enough variety and attention that our lives don't become one long sequence of interchangeable days.
Learn something unfamiliar.
Visit somewhere you've never been.
Talk to someone you normally wouldn't.
Take a different route home.
Read something outside your usual interests.
Put the phone away for an hour.
Have a long conversation without checking the time.
Do something that makes you slightly uncomfortable.
Not because you need to “optimize” your life—because you need to actually experience it.
The Strange Paradox of Time
There is a beautiful paradox here.
When we are young, we desperately want time to move faster.
We want to grow up. We want independence. We want our own money, our own choices, our own lives.
Then we grow up and start wondering where all the time went.
The child says, “I can't wait to grow up.”
The adult says, “Can we please slow this thing down?”
Unfortunately, life doesn't come with a speed-control button.
There is no setting called “2x slower, please.”
So perhaps the only thing we can control is how much of the time we actually notice.
Don't Just Count the Years
We often measure life in birthdays, years, degrees, promotions, salaries, and milestones.
But perhaps there is another way to measure it.
Measure it in conversations you still remember.
Places that changed your perspective.
People who made ordinary days special.
Things you learned for no particular reason.
Laughs that arrived at completely inappropriate moments.
Sunsets you actually stopped to watch.
Meals that lasted longer because nobody was in a hurry.
Those moments may not look important on a calendar.
But they are often the moments that make a life feel lived.
Final Thoughts
Time probably isn't moving faster.
Our lives are simply becoming fuller, more familiar, and more repetitive, while the years become smaller pieces of a much longer story.
We cannot slow the clock.
We cannot negotiate with Monday.
And unfortunately, there is no customer-care number for requesting an extension on a particularly good year.
But we can pay more attention.
We can create new memories.
We can break the routine occasionally.
We can spend less time waiting for the next milestone and more time noticing the ordinary moments between them.
Because one day, today's ordinary Tuesday may become one of the days we wish we could experience again.
And perhaps that is the real lesson about time:
We don't always notice its passing while we're living it. We notice it when we look back.
So maybe the goal isn't to make time move slower.
Maybe the goal is to make the time we have harder to forget.
