Help with date in bash script for loop from YYYYMMDDHHMM

Hi everyone

I need some help

I want to create an script which does some processing

it takes the two arguments 201901010000 and 201901020200 - so YYYMMDDHHMM

I want to split processing into hours from start until end,


I dont get why this works but when I add to a future variable hours + minutes it stops work

Code:
d=$(date -d "20190308 + 1 hour" '+%Y%m%d%H%M'); echo $d            
201903080100

Code:
d=$(date -d "201903081000 + 1 hour" '+%Y%m%d%H%M'); echo $d 
date: invalid date `201903081000 + 1 hour'

All help is much appreciated, going to share also the script tomorrow morning, but I need to figure this one out
