This is really more of a usage note than a grammar issue, but I was too lazy to come up with a headline, so grammar it is.
Today we’re talking about whether to use historic or historical. Like most either/or usage questions, it depends on what you’re trying to say.
Historic refers to what’s important in history:
Aaron’s superhuman effort led the EWU marching band to a historic victory over KZZU at the 1989 Taco-Eating Championship.
And historical refers to whatever existed in the past, whether regarded as important or not:
Dismayed by the historical anomalies he saw at the local Renaissance Faire, CK vowed never to return.
