Technically anything after 12am would be "morning" because it's a new day.
However, generally early morning would sometime between 3 and 5. If you wake up at 3am, it's early morning. If you go to sleep at 3am, it's late at night.
Anything after 5am is just morning (unless you're being goofy and calling everything night because you didn't sleep).
(These aren't specific rules, just how it is in my region - other people might be totally different)
Actually I wrote it like that… But I wasn't sure if it was the right term, so Google Translate corrected me to that…
Are you saying Google Translate trolled me?
Yes, it did.

3am is an "ungodly hour" no matter your sleep schedule
