Don't confuse every day (two words) with everyday (one word).
Every day is used as an adverb and means ‘each day':
✗ Technology is advancing everyday.
✓ Technology is advancing every day.
✗ Everyday, when they go back home, the first thing they do is turn on the TV.
✓ Every day, when they go back home, the first thing they do is turn on the TV.
Everyday is an adjective meaning ‘common or normal', and it always comes before the noun:
✗ When people are in love they are able to leave every day life behind.
✓ When people are in love they are able to leave everyday life behind.
