Scientists explain why the year 2025 flew by in an instant: the paradox of time perception.

According to ТСН: Why did the year 2025 pass so quickly? Scientists have found that our brain does not have an internal clock — it measures time by the number of bright events and emotions. Psychologists explain why routine days seem long, while years feel short.

To understand why the feeling of time flow can be distorted, it is important to realize how our brain actually measures time.

The term 'time perception' is not quite correct, as time is not a physical object that can be felt. Our senses react to various signals from the surrounding world, but there are no similar signals for time that the brain could capture.

How does the brain determine time?

The brain does not measure time directly — it draws conclusions about its flow by evaluating duration based on changes in circumstances.

Unlike a clock, the brain does not have uniform 'ticks'. To realize how much time has passed, it counts the number and intensity of events.

For example, a period filled with emotions and activity is perceived as longer. In studies, a brief flash of an image is considered longer than a static image of the same duration.

People who have witnessed extreme situations — such as traffic accidents — often feel that time slows down. In a well-known experiment, participants fell backward into a net from a height of over 30 meters. Assessing the duration of this stressful moment, they reported significantly larger metrics than when observing another person's fall.

Strong emotions enhance attention, allowing the brain to form detailed memories. Analyzing these memories later, it exaggerates the actual time that has passed.

Does time really fly?

To understand where the months go and why a year seems shorter, it is important to distinguish between two types of time perception: retrospective — when we evaluate the past, and prospective — when we feel how quickly time passes now.

Waiting in line or at the doctor’s office seems endless, while time spent on a favorite activity passes unnoticed. The reason lies in where we focus our attention. The more we concentrate on time, the slower it seems.

The saying that time passes faster when we are having a good time can be explained by the fact that distracting activity is important. When our thoughts are occupied, we do not notice how minutes blend into one. Instead, boredom or continuously watching the clock slows down the perception of time.

Why does routine 'eat up' years?

The difference in the feeling of time 'here and now' and the assessment of the past explains the saying: 'days stretch long, while years fly by quickly'. With age, this feeling intensifies.

In childhood and youth, life is filled with novelty: important events, new experiences, significant changes create a rich archive of memories, resulting in the perception of this period as prolonged. As the years go on, many daily tasks become automated. Routine tasks lose their novelty and emotional intensity, and as a result, days may seem slow and monotonous.

Such monotonous days leave few vivid memories. When at the end of the year the brain tries to evaluate its duration, it cannot find enough events, and the year is perceived as short.

Therefore, realizing that it is already December, we are surprised at how quickly time has flown.

How to slow down the feeling of time?

Slowing down time in the moment is not hard, but it is unpleasant: it is enough to be bored, wait, count, or observe monotonous processes.

Preserving the brightness of memories is more difficult. The first way is to keep a diary, view photographs, and revisit past experiences. The second way is to actively seek out new impressions. Journeys, discoveries, unusual solutions create vivid memories that 'stretch' the year in memory. Then your internal clock will work quite differently.

We remind you that earlier we discussed how 'Black Friday' works. It has become a global psychological phenomenon that literally makes our brain demand purchases. The key role in this belongs to the reward system: when a person sees the word 'sale' and bright banners, the brain receives a signal of pleasure, blocking rational thinking.
