I'am no translation expert, but generally I find cada is often used when we say each in English and every is used more when you would say todo(s). That is just a general thing I noticed of course there are times when you would use cada, but we would say every. Sorry if I confused you the other day with "every day and everyday" I don't usually right those words I use them more when I speak. Usually I prefer to write "daily" for "everyday" and "each day" or "all the time" for "every day".

Each is used if you want to be very specific about an individual thing; every means a whole group of things. They're often interchangeable. Examples: Each of these houses has a new front door. Every house on this street is blue. Those peaches cost one dollar each. I have enjoyed every movie that I've seen this summer. Many times you can use either one: I bought drinks for each person in the bar. I bought drinks for every person in the bar. Sometimes we use them together, as a way of showing emphasis: I bought drinks for each and every person in the bar. We also use "every" in compound words, like everyone and everything, but we don't use "each" that way.

Gracias Neil :)

"Each" hace hincapié en la individualidad de las personas u objetos, mientras que "every" trae a la mente el hecho de que existe un grupo. "Each" corresponde a "cada" (uno/una)", mientras que "every" corresponde a "todos/todas".

Each is both pronoun and modifier- When you walk each foot leaves the ground before the other comes down. There are five necklaces - You may take one of each. Every is determiner, it is used when referring to all the members of a group of three or more- The police want to interview jeweler about the theft.
