Beginner Mob Farm chunk borders/corners

[SCamp]

I want to start a mob farm, but I need to know what the chunk borders are for orientation. Can someone give an example of 4 (x,y) tile coordinates at the center of 4 chunks as an example?

Alternatively, is there a command that shows a chunk grid like minecraft?

from what I've seen online, chunks/cells are 16x16, so any map coordinate that is a multiple of 16 is going to be a chunk edge. the one thing i'm not clear on is whether the count starts at 0 or at 1.

but to give you an example with coordinates, i built my own starter mob farm so the center of it is at 47:15, 48:15, 47:16, 48:16

https://maptool.ceschmitt.de/# load your map and select "show mob grid" (the tool isnt up to date for the distances of poi/boss)
iirc: your starting point is 0:0, so you have the first from 0:0 > 15:15, from 0:-1 > 15:-16, -1:-1 > -16:-16 and -1:0 > -16:15 (NE/SE/SW/NW)
