^. is the 1st char, put into () (protected with \) to store in \1 
which gets uppercased with \U.

Julien wanted monday -> Mon, it seems. That's what the cut does: take 
three bytes. We can loose the cut, too:

echo monday | sed 's/\(^.\)\(..\).*/\u\1\L\2/'

which matches 2 more characters and lowercases those with \L
