321
Numbers before liftoff
A countdown sequence reaching its end, typically preceding an action or event: Three, two, one—go!
Often written as 321 in casual contexts to signal imminent launch, start, or moment of truth.
The numbers represent the final seconds before something happens—a rocket lifts off, a race begins, a new year arrives.
