Shell script to increment hour in date-time

Can anyone help me to add only the hour part in below date/time format:

For instance, starting with 20 August 10:00am

2016-08-20-10

I would like to increment only the hour part, so that I get:

2016-08-20-11
2016-08-20-12
2016-08-20-13
etc.

stopping at a specified date, such as 2016-08-21-08

I figured out the solution to my own question. See below:

date=(2016-08-23-0 2016-08-23-1 2016-08-23-2 2016-08-24-0 2016-08-24-1 2016-08-24-2)
date_arr=(2016-08-23-2 2016-08-24-2)

for ((i=0; i<"${#date[@]}"; i++))
   do
       if [[ " ${date_arr[*]} " == *"${date[i]}"* ]]
         then
            for ((j=0; j<=3; j++))
            do
                    echo "${date[i]}$j"
            done
       else
            for ((k=0; k<=9; k++))
            do
                    echo "${date[i]}$k"
            done
       fi
   done
