When to use " everyday" and when to use " every day"?Do they have the same usage?
Thanks for your time!

Question

Answer

- every day: every (determiner) + day (noun)
= 'every' is used with singular nouns to refer to all the members of a group of things or people (every day, every minute, every student...). So it means each day.
'His father bikes to work every day.'
'Ever day seemed the same to him.'
'We work every day except Sunday.'

- everyday: is a single word and is an adjective, so it's the one that is used in front of a noun to describe something as normal or commonplace.
'everyday life'

Answer

everyday是形容词，“每天的，常有的,司空见惯的”的意思，只能用作定语。
She has only an everyday story to tell.
她讲不出什么新鲜玩意儿。

而every day是一个副词词组，只能用作状语。 
She gets up early every day.
她每天起床很早。
