Can I suggest a case statement to simplify to logic.

Use break statement to leave while loop. Also notice some glob matching to allow upper or lower case first letter and quit/exit/done to leave.

Code:

while true
do
   echo "Please choose a month from January to December and that month will display which holiday is related to that month."
   read month
   case "$month" in
        [Jj]anuary)   echo "Martin Luther King Day is in the month of January." ;;
        [Ff]ebruary)  echo "President's Day is in the month of February." ;;
        [Mm]arch)     echo "There is no holiday in the month of March." ;;
        [Aa]pril)     echo "There is no holiday in the month of April." ;;
        [Mm]ay)       echo "Memorial Day is in the month of May." ;;
        [Jj]une)      echo "There is no holiday in the month of June." ;;
        [Jj]uly)      echo "The Fourth of July is in the month of July." ;;
        [Aa]ugust)    echo "There is no holiday in the month of August." ;;
        [Ss]eptember) echo "Labor Day is in the month of September." ;;
        [Oo]ctober)   echo "Columbus Day is in the month of October." ;;
        [Nn]ovember)  echo "Thanksgiving one of the most wonderful holidays, is in the month of November." ;;
        [Dd]ecember)  echo "Christmas is in the month of December." ;;
        [Dd]one|[Ee]xit|[Qq]uit) break ;;
        *)            echo "This month does not exist."
    esac
done

Also quick note on posting code to this forum, if you put [code] and [/code] tags around the code it stops any formatting (like indenting) from being lost as you can see above.

holidays(4)							   File Formats 						       holidays(4)

NAME

       holidays - prime/nonprime table for the accounting system

SYNOPSIS

       /etc/acct/holidays

DESCRIPTION

       The   /etc/acct/holidays file describes which hours are considered prime time and which days  are holidays.  Holidays and weekends are con-
       sidered non-prime time hours.  /etc/acct/holidays is used by the accounting system.

       All lines beginning with an "*" are comments.

       The  /etc/acct/holidays file consists of two sections.  The first non-comment line defines the current year and the start time of prime and
       non-prime time hours, in the form:

       current_year	 prime_start	  non_prime_start

       The remaining non-comment lines define the holidays in the  form:

       month/day     company_holiday

       Of these two fields, only the  month/day is actually used by  the accounting system programs.

       The  /etc/acct/holidays file must be updated each year.

EXAMPLES

       Example 1: Example of the /etc/acct/holidays file.

       The following is an example of the /etc/acct/holidays file:

       * Prime/Nonprime Table for the accounting system
       *
       * Curr	  Prime     Non-Prime
       * Year	  Start     Start
       *
	 1991	  0830	   1800
       *
       * only the first column (month/day) is significant.
       *
       * month/day    Company Holiday
       *
	 1/1	      New Years Day
	 5/30	      Memorial Day
	 7/4	      Indep. Day
	 9/5	      Labor Day
	 11/24	      Thanksgiving Day
	 11/25	      day after Thanksgiving
	 12/25	      Christmas
	 12/26	      day after Christmas
