What's the difference between "every other day" and "every two days"? 
What's the difference between "every other day" and "every two days"?

Answer

Technically, there is no difference! Just two different ways to say it. :)

Answer

下面的回答有错误。"every other day" is not necessarily "every two days," though it can be. 比如说：如果我三天以前打了网球，今天打了网球，四天以后又打了网球，我可以说："I play tennis every other day." 所以“every other day"的意思就是“经常，可是不是每一天做的“。
