consider a shorter bit of arithmetic:
Code:
# the the age of the file using epoch seconds
fileage=$(( $(date +%s) - $(date -r min.h.bak +%s) ))
# age expressed as hours:
echo "hours = $(( $fileage / 3600 ))"
# age in days:
echo "days = $(( $fileage / 86400 ))"

You errors have a space between the variable name and equal symbol in an assign statement
Code:
var ="bad"
var= "bad"
var = "bad"
# no spaces either side of the equals symbol.
var="correct"

You have a logic problem using %H for hours - file going over midnight i.e., yesterday at 2300 and today at 0106 will give you a negative number
