I just went from an iPhone 6s running iOS 15 to an iPhone 13 running iOS 17, and something I really didn’t like about the new phone was the font and thickness of the clock (which I figured out how to change so it’s back to being near identical to the old one just bigger), but just the fact that the date is above the time bugs me way more than it probably should and I don’t see a way to move it. I honestly don’t know why it bugs me so much.
The only thing I haven’t figured out how to change is the location of the date which is arguably the least annoying thing so far lol. I can’t find anything on Google about moving stuff on the lock screen around so I might just have to get used to it I guess.
I also really don’t like the notifications being at the bottom but it looks like there isn’t a way to change that either, I found other people had asked already.
To edit, tap and hold on your Lock Screen. Then tap Customize at the bottom, select Lock Screen. There, you can change size/font/color of the time as well as change the widgets that might appear above and below the time
