set [new month v] to (((original month) + (months to add)) mod (12))
ask [Type in a number between 1 and 12 for a month of the year:] and wait

say (join (join (months to add) (join [ months after ] (item (original month) of [months v] :: list))) [ is December. ])

say (join (join (join (join (months to add) (join [ months after ] (item (original month) of [months v] :: list))) [ is ]) (item (new month) of [months v] :: list)) [.])

Hints
• Make variables called “original month” and “months to add” and set their values to the inputs entered by the user. Make a variable called “new month” and set its value to the sum of the “original month” and “months to add” modulo 12.
• Make a list called “months” and add the 12 months; January, February, March, April, May, June, July, August, September, October, November and December to your list (list of length 12).
• Display the output as December if the value of “new month” is equal to 0 otherwise display the month at the index “new month” as the output.
