What Does T Minus Mean?
At its core, T-minus means the amount of time remaining before a specific event happens.
The “T” stands for “time.”
The word “minus” means before.
So when someone says:
T-minus 10 minutes
They mean:
There are 10 minutes left before the event begins.
T-Minus Definition (Simple and Clear)
T-minus refers to a countdown point that measures time remaining before an event reaches zero, also known as T-0.
In simple words:
- T-minus = time left
- T-0 = the moment the event starts
This explains why the phrase feels urgent. It always points forward. Something is about to happen.
