Of course they do, the commands are identical. Did you mean "6 days ago"
in the second case?

Perfectly correct.
`%V'
week number of year with Monday as first day of the week as a
decimal (01...53). If the week containing January 1 has four or
more days in the new year, then it is considered week 1;
otherwise, it is week 53 of the previous year, and the next week
is week 1. (See the ISO 8601 standard.)
$ date -d "8 days ago" '+%G-%V'
2004-01
`%G'
The year corresponding to the ISO week number. This has the same
format and value as `%Y', except that if the ISO week number (see
`%V') belongs to the previous or next year, that year is used
instead.
