Why Does Time Seem to “Fly By”?

Have you ever wondered why time seems to pass quickly or “fly by”? There are several psychological and scientific explanations for this phenomenon:

Explanation 1: Perception of Time

Our perception of time changes as we age. When we’re young, time seems to pass slowly because we’re experiencing everything for the first time. As we get older, we’ve experienced more, and time seems to pass more quickly.

Explanation 2: Routine and Monotony

When we’re engaged in routine tasks or activities, time seems to pass more quickly. This is because our brains are not actively processing new information, and we’re not creating new memories. Therefore, time seems to “fly by.”

Explanation 3: Time Estimation

When we’re engaged in enjoyable activities, time seems to pass more quickly because we’re not constantly checking the clock. Conversely, when we’re engaged in unpleasant tasks, time seems to pass more slowly because we’re constantly checking the clock and estimating how much time is left.


In conclusion, “flies by” is the correct spelling of the phrase that describes the passage of time. While it may seem like a simple phrase, many people make mistakes when using it. By understanding the correct usage of “flies by,” you’ll be able to communicate more effectively and avoid common mistakes.
