AsSalamOAlaikum WaRehmatuAllah WaBarkatuhu
This is what i do...
Well akhi down south, Esha starts at 10.30 and Fajr starts at 3.11.
Esha should be performed by midnight. Only if you have a valid excuse then you can pray Esha between midnight til Fajr.
Its always best to pray in Jamaa', so see what times they do it at your local Masjid and follow that. Here the jamaa' times are 10.45 and 4.15. Alhamdulillah
FiAmaaniAllah
