Why Does Time Feel Like It Flies or Creeps?

Have you ever wondered why the last day of school feels like it takes forever, but holidays seem to vanish in a blink? That is because time does not tick inside your head like a metronome. It changes shape based on what your brain is doing.

When you are playing with new toys or learning something cool, your brain writes down lots of detailed memories. Because there are so many good things to remember, those days feel long and full. However, when you look back at them later, they seem short because the novelty makes them blend together.

If you stand still and wait for a bus, every second feels heavy. Your brain is not busy recording new things, so it just watches the clock. This makes time feel like slow molasses dripping down. As we grow up, life becomes more routine. We do the same things every day, so fewer memories are saved. This is why time seems to speed up as you get older.

Big surprises also trick your brain. If you catch a falling glass, your mind records that moment in high detail. Later, it feels longer than usual because there is more information stored about it.
