What Is the Meaning of Time Flies?

If someone says, “Time flies,” no one thinks time is actually flying. Instead, time flies is an idiom, an expression that means something other than a literal interpretation of the words.
As mentioned earlier, time flies just means that time can pass very quickly. This is especially the case if you’re very busy or when, as an extended version goes, you’re having fun. We think of flight as fast, so it makes sense to say that time can fly.
No one knows when people first started using time flies in English. However, we do know that it’s a translation of the Latin tempus fugit. No one knows exactly when that started, either. But it’s been around for a long time; it’s in the works of the poet Virgil that were published around 29 B.C.
Example sentences:
- The last time I saw you, you were only up to my waist, and now look at you! Time flies!
- It feels as though we just started, but we’ve been at this for four hours. How time flies!
- My, time flies! It seems that just yesterday, you were in kindergarten, and now you’re all grown up!
- Becoming a grandparent is often a jolting reminder of how time flies.
- It’s already midnight? Time flies when you are busy.
- Time sure flies when you are preoccupied.
- The slideshow juxtaposing the graduates’ pictures with their baby pictures was a classic example of how time flies.
When and How to Use Time Flies
You can use time flies in both spoken and written conversations.
The examples show time flies can be part of a longer sentence and can stand on its own. You can even add an exclamation point. When you use it on its own, make sure to capitalize ‘time'” and punctuate the expression correctly since it’s a complete sentence.

- You’ve been doing something for a lot longer than it feels like.
