Wondering how EDD differs of DOB

Hello. I gave birth in august 2023 I chose to go with elective C-Sect and he’s my first born. Nothing wrong with going with csect just personal preference. For me my pain tolerance was low hence I didn’t wana go through natural birth. For csect, you will need to book the operating theatre hence you can’t really “delay” the birth. But if baby come out earlier, it’s considered as emergency csect which may add some cost to the birth. Csect recovery is not as scary as what others say, I managed to get off the bed on the 2nd day and function as per normal (do note I’ve 0 pain tolerance). I’m a month pp and recovery has been quite easy for me even without a confinement nanny.
