Do you not care which specific commit on the specific day
(or other time interval)?

Is this a one time thing? A regular procedure for varying
dates? Something else?

About how long ago is the date in question? Pre-git?
Post-git?

Is the branch known? main? A quarterly? (Which quarterly?)

If it is a one time thing and recent enough, looking at
the commits reported for the month via, say, something like:

https://lists.freebsd.org/archives/dev-commits-ports-main/
or:
https://lists.freebsd.org/archives/dev-commits-ports-branches/

should allow finding a commit-hash-prefix for something from
the date in question. After that: normal git procedures. But
it is not clear if your context fits that.
