A proton is stable, as far as we know, and has no half-life.

I believe it is all dependent on what type of element that proton belongs to. The only element I know of that has a single proton, would be Hydrogen and the half life for it's isotope (H^3) is roughly 12 or so years.

Cheslar was sort-of correct. Attempts to measure decay of protons have never been able to observe it happen. The conclusion from these attempts was that the half-life, if it is not infinite, is more than 10^33 years.
For comparison, the accepted age of the universe is only about 1.4 x 10^7 years.

Protons don't have a half life.

Around 10^35 years.
It is supposed to be one of the largest known subparticles Half-lives.

Do you mean the half-life of an atom? Depends on the atom. Well, what isotope the atom is.
Like, for carbon dating? What is it for? It only works for radioactive isotopes (most elements aren't radioactive.)
