on  和 by

On and by are very confusing because
1)on can be adj,adv and preposition
2)by can be adv and preposition.

Preposition is always added before a noun,pronoun or noun phrase to connect with another word.

you should write i will come to you tomorrow instead of on tomorrow.
On friday,on monday are correct,but on today on yesterday or on tomorrow is wrong.

Tomorrow can be a noun or adv.
Tomorrow is another day.(tomorrow here is a noun.)
I will think of it tomorrow.(tomorrow here is adverb,it describes the verb think.)

On tomorrow

I will finish it today or i will finish it by today?
i presume the first one is correct,second one may be correct,but i think it is redundant.

By ( shows not later than,at or before)
I will finish it by 5 o'clock.
