OK, thanks, I guess the --before part answers my question: so to get revision "rev" back at date "YYYY-MM-DD" (always using first parents) I'd do

git rev-list rev -n 1 --first-parent --before=YYYY-MM-DD

as in:

git checkout "`git rev-list rev -n 1 --first-parent --before=YYYY-MM-DD`"

It's a bit of a mouthful, but it does what I want (although I still think a syntax such as rev~@{YYYY-MM-DD} or rev~{YYYY-MM-DD} or whatever might prove useful: I imagine I'm not the first person to wish for something of the sort).

Thanks,
