Finding All Dates Between Two Dates in Bash

Question

I am trying to get all the dates that fall between a start and end date. This is what I did

start="2022-03-02"
end="2022-03-07"
while [[ $start < $end ]] 
  do 
     echo "$start"
     start=$(date -d "$start + 1 day" +"%Y-%m-%d") 
done

This results in an error

usage: date [-jnRu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS]] ... 
            [-f fmt date | [[[mm]dd]HH]MM[[cc]yy][.ss]] [+format]

What is it I am missing?

You can try this if you using on MacOs

date -j -v+1d -f %Y-%m-%d $start +%Y-%m-%d
