As far as I can find, 每天 is slightly more formal?

Yes, 每天 is slightly more formal.

And sometimes, 天天 can be used to emphasize "every day is too often": 我每天 (it's OK) 去工作,你却天天 (too often) 逃课!

  • I think "天天" have special rhythm so it uses more likely to be used to express emotion. No matter good or bad.

The latter is used solely in spoken Chinese, while the former may be used in writing.


我每天都学习汉语。 is equivalent to 我天天学习汉语

Speaking the former one sounds (sometimes) a little weird, but not much. While writing the latter one is not usually seen outside of quoting others.


Essentially, there is no difference. 天天 emphasizes more and can highlight the object's persistence in doing something.

They mean the same thing, but the former is often used in writing
