For this particular case, you'll have better luck with: $ date -d "1940-06-01 12:00" +"%Y-%m-%d" but this sort of approach does not work in general, because 12:00 does=20 not always exist either. In other words, the 'date' command is not=20 suited for calendrical arithmetic in general, only for time arithmetic.
