At the crack of dawn (looking for idiomatic translation)

Question

I do understand what that means but I am looking for the Persian equivalent, something like spoken Persian, idiomatic or slang kinda thing.

For example what would be your best Persian equivalent of this:

 

Every morning, Nader wakes up at the crack of dawn

 

Thank you guys
