The post Why Time Seems to Speed Up as You Get Older, According to Researchers first appeared on Crafting Your Home.
Any American over forty will recognize the strange calendar trick: Halloween candy is barely unwrapped before Christmas lights are going up.
The holidays seem to arrive faster because the years themselves can begin to feel compressed. That sensation has become especially easy to notice in adulthood, when familiar rituals repeat and fewer experiences feel genuinely new.
Even the way people decorate for the holidays can reflect that familiarity. A recent survey found that 36% of Americans spend nothing on new holiday decor in a typical year, while another 37% spend between $1 and $100. Older adults are also more likely to say they already have enough decorations, having accumulated them over decades.
That matters because psychologists have long investigated a related question: why do familiar years seem to disappear faster in retrospect? One influential explanation is that novelty and memorable experiences give the mind more distinct markers to organize a period of time. When life becomes more repetitive, entire stretches can later feel as though they passed in a blur.
Researchers have been debating the phenomenon for more than a century, and there is no single explanation that accounts for everyone. What makes the effect interesting is that the feeling is real even though the clock itself has not changed.
The math was worked out before your grandparents were born
French philosopher Paul Janet proposed a formula in 1897 that still holds up: each year of life becomes a shrinking fraction of the total years you’ve lived, so it registers as proportionally smaller. A year for a five-year-old is one-fifth of their life so far, but a year to a fifty-year-old is one-fiftieth of it, so it passes roughly ten times faster. Extend that math and an 80-year-old is living each year at nearly sixteen times the perceived speed of a five-year-old.
Janet’s arithmetic explains the shape of the problem. It doesn’t explain the mechanism, which is where things get less flattering.
Your brain is quietly editing your life down
Psychologist William James got there first, in 1890, arguing that time compresses in adulthood because life stops handing you firsts. He wrote that when you measure time in memorable milestones like a first kiss or a first day of school, their disappearance in adulthood causes the days and years to smooth out and collapse. Grim phrasing for a Victorian academic, but the underlying claim has aged well.
Modern researchers at the University of Michigan built on it with a less poetic metaphor: frames per second. Fewer novel experiences mean the brain processes fewer distinct frames, so time feels like it’s passing quicker, like a flipbook with fewer pictures to flick through before hitting the end. University of Michigan psychology professor Cindy Lustig has pointed to the flip side of that coin: a period packed with events makes time stretch out and feel very long, precisely because there’s more to differentiate one day from the next.
None of this is about age itself. It’s about routine.

The uncomfortable part: it may not be about memory at all
Here’s where recent research gets harder to sit with. German psychologist Marc Wittmann has spent two decades tracking how people report the speed of their lives, and his newest findings complicate the tidy story about nostalgia and vivid memories.
Older adults in his research did not describe their memories as fainter or less vivid than younger people’s. If anything, the opposite showed up: what they did retain felt richer and more emotionally resonant. The romantic idea that aging simply dulls the past doesn’t hold. What’s declining instead is subtler, and less flattering to hear.
A 120-person study led by Alice Teghil alongside Wittmann, spanning participants aged 20 to 91, found that the strongest predictor of feeling the last decade speed by wasn’t the volume or richness of memories people could recall. It was their score on delayed memory recall tests, a marker of how well the brain currently encodes new information day to day. Weaker encoding tracked with a faster-feeling decade, regardless of how meaningful the person’s memories were.
Wittmann attributes the decline in encoding the unremarkable moments of daily life to cognitive decline, a process that can begin as early as someone’s thirties. That’s not a midlife or senior phenomenon. It’s already underway for a large share of working adults reading this.
It’s not just you, and it’s not just Christmas
Skeptics might assume this is a WEIRD-sample problem, the kind of finding that only holds up among surveyed Americans and Europeans. Psychologist Ruth Ogden tested that assumption directly. In a study of 918 adults, 77% agreed that Christmas seems to arrive more rapidly every year, while only 9% disagreed. Ogden’s team then asked an Iraqi sample the identical question about the approach of Ramadan and got a strikingly similar distribution of answers.
The specific holiday changes. The math around it, and the sensation attached to it, apparently does not.
A wrinkle that complicates the fix
The instinct here is to reach for the obvious prescription: chase novelty, and the years will slow back down. The research doesn’t let that off the hook so easily.
Engaging in something new tends to make time pass more quickly while you’re inside the experience, not more slowly. Only in retrospect does the novel activity stretch out and feel like it lasted longer than the routine around it. So a first, unfamiliar week abroad can genuinely feel like it flew by in the moment, and still be the week you remember most vividly a decade later as the one that took forever.
That’s an inconvenient distinction for anyone hoping for a tidy trick. The relief isn’t immediate. It’s retroactive, paid out later to the version of you doing the remembering.

What this actually asks of you
Put together, the research points somewhere less comfortable than a listicle of hacks. Janet’s math says the acceleration is structurally guaranteed and will not reverse. Wittmann’s newer data says part of the cause is a quiet decline in how well your brain files new information, starting earlier than most people assume. And the novelty research says the payoff for fighting back doesn’t arrive until later, if it arrives at all.
None of that is an argument for resignation. It’s an argument for taking the flipbook metaphor literally: the years with fewer distinct pages are the ones that vanish fastest, and the only lever anyone has found that reliably adds pages is doing something the brain hasn’t filed away yet, on purpose, before the pattern-recognition sets in and does it for you.
