We pronounce hour as OUR and not H-OUR. So the first sound is that of O which is a vowel. Therefore the usual rule of using "an" before vowels applies in this case.

Because the "h" in hour is silent, so the first sound you actually utter is the vowel sound "a".

While pronouncing it, the 'h' is silent in hour, and 'o' is a vowel, so we say 'an' hour.

Because we don't pronounce the h.
Also note how some words beginning with u have an,
an umbrella, an umbical cord
But if we say 'yu' we use a
a university, a unicorn

Because the 'h' is silent is the British pronounciations of most 'h' words, and as such it makes speech flow more easily to use 'an' instead of 'a'.
American use is just a holdover of this custom.

what determines whether we use 'a' or 'an' not only has to do with the letter it preceeds, but also how it is pronounced.
IE: you wouldn't say, " Sally had a S.A.T score of 1600."
You would say, "Sall had an S.A.T. score of 1600."
Got it?

It's the sound that follows a or an that is important, not the letter.
