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

NAME
rbash - restricted bash, see bash(1) RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow- ing are disallowed or not performed: o changing directories with cd o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV o specifying command names containing / o specifying a file name containing a / as an argument to the . builtin command o specifying a filename containing a slash as an argument to the -p option to the hash builtin command o importing function definitions from the shell environment at startup o parsing the value of SHELLOPTS from the shell environment at startup o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators o using the exec builtin command to replace the shell with another command o adding or deleting builtin commands with the -f and -d options to the enable builtin command o using the enable builtin command to enable disabled shell builtins o specifying the -p option to the command builtin command o turning off restricted mode with set +r or set +o restricted. These restrictions are enforced after any startup files are read. When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script. SEE ALSO
