count line changes with git?

Question

Is there a simple way I can ask git for the amount of lines I added (or add and removed) in a specific date range?

I'm using git on Windows, Linux and TortoiseGit(Windows)

Building upon Seth Robertson's answer, (+1 Seth!) awk will tally up the columns for you:

% git log --stat --author $(git config --get user.email) --since="last year" --until="last month" | awk -F',' '/files? changed/ {
    files += $1
    insertions += $2
    deletions += $3
    print
}
END {
    print "Files Changed: " files
    print "Insertions: " insertions
    print "Deletions: " deletions
    print "Lines changed: " insertions + deletions

}'
