To resolve that particular one-word vs. two-word conundrum, you must first determine what you mean to say — and that isn’t always easy. However, the difference between “everyday” and “every day” is easy to remember.
“Everyday” (one word) is an adjective to describe the average, mundane, quotidian, run-of-the-mill, and so on.
Example: I wear my everyday shoes to work.
“Every day” (two words) is an expression that means each day and should be used for everything other than the quotidian.
Example: I wear shoes to work every day.
You could use both versions in one sentence — “I wear my everyday shoes to work every day” — but that would be downright nutty.
An easy rule of thumb: if you can substitute “each day” and your sentence still makes sense, use two words.
It’s not every day I can offer such an everyday rule.
