$line =pqr ffg , Long Beach, california, Sep. 12-14
$line = Hello , St. Louis, Missouri, Mar. 29-31
$line = hello, How are u

I need to remove the last part from the string which contains month information using a general regular expression, which is suitable for all the lines and the line which doesn't have any month information should remain as it is.
