What is 38 microseconds per day?

"38 microseconds per day is like having a super tiny advantage that adds up over time."

Imagine you're racing your friend to the playground every day. You both start at the same time, but you get a little head start, just 38 microseconds. A microsecond is super short, it’s like one millionth of a second! If you think about how fast you can blink your eyes or tap your toes, that's how tiny a microsecond is.

Now imagine this tiny advantage happens every single day. It might not feel like much at first, but over time, like months or years, those little seconds start to add up. It’s like getting a few extra steps in the race, just because you had that teeny head start each day.

How it feels in real life

Think about your favorite toy. If it took 38 microseconds for it to spin once, and you watched it go around all day long, that would be like watching it move really slowly, but constantly. That tiny amount of time is what we're talking about when we say 38 microseconds per day. It's small, but it’s there, every single day!

Examples

  1. Imagine a clock that loses just one second every year, it's like this tiny fraction of time.
  2. If you blink once every minute, 38 microseconds per day is the smallest difference you'd notice over years.
  3. It’s how some clocks keep time so precisely they can stay accurate for thousands of years.
