Question

What is the difference of 엊그제 and 그저께?
1) What is the difference between the two? 
2) Can I use both of them as 'day before yesterday'?

Thank you^^

Answer

엊그제 literally means 어제(yesterday) + 그저께(the day before yesterday), and it's used only if the correctness doesn't matter.

You should use 그저께, if you want to be specific on "the day before yesterday".

Answer

엊그제 means "a couple of/ a few days ago", while 그저께 means "day before yesterday".
I hope this helps!
