ELI5 Why are we collectively feeling time move faster?

Whenever we are at the end of a month, I feel like saying “wow, really, already?!” Like 2026 feels like it just started yet we are more than half way through. Even 10 minutes before used to feel way longer than 10 minutes now, it feels like 10 minutes are the new 5 minutes. I’ve noticed that this is a common feeling amongst many people and I’m curious about why.
