Code:

monthyearnow=$(date '+%Y')
should be
yearnow=$(date '+%Y')

Code:

#!/bin/bash

read -p "Enter your birth year. Example: 1900 :  " year
read -p "Enter your birth month. Example: 06    "  month

yearnow=$(date '+%Y')
monthnow=$(date '+%m')
agey=$(expr $yearnow - $year)
agem=$(expr $monthnow - $month)

if [ $agem -lt 0 ] ; then
   agem=$(expr $monthnow - $month + 12)
else
   agem=$(expr $monthnow - $month)
fi
echo "You are $agey years and $agem months old!"
