What Is the Difference Between While and Whilst?

Typically, Brits use whilst and Americans use while. That's the main difference. When used as a conjunction or an adverb, while and whilst are interchangeable: There wasn't much Stanley could do while he waited.

What is wrong with whilst?

You can't write “a whilst” – because “while” is being used as a noun. You can't use “a while” and “awhile” interchangeably – they mean different things.

Is Whilst past tense of while?

I was given to understand that "While" is the present tense and "Whilst" is the past tense. For example: "He sings while he is is in the shower." and "When he was alive, he sung whilst in the shower."
