"A his-toric day"
"An his-toric day"
Both seem to work correctly with American pronunciation.
Journalists and films seem to use "an historic" with an American accent, which breaks the rule but still feels correct.
For most words the indefinite article is clear. This one feels weird.
No it doesn't. If I pronounce the "h", then using "an" sounds weird. If I don't, then "a" sounds weird.

Curious if you have a link to a video of this, I can't imagine it sounding correct.

For example:
I'm pretty sure "an historic" is the norm in American media, not the other way around.
"An historic" is certainly used in the US, but it's wrong in all contexts.
