the "'" single-quotes normally are used to 'hide'
stuff from the shell interpretting it, so you merely
need to 'un-hide' the variable from the shell....
oye, that took a moment, to note the silly
in the syntax there - since you are saying
from the line that Matches $MONTH to the end
delete...
had you wanted to have all lines from the beginning
till you saw that token then you could have tried
sed '/'$MONTH'/q' file
hence telling it to quit when it sees that match.
