Where 7 days shows up
One week, and the only conversion on this site with nothing to round. The seven-day week is the one calendar unit with no astronomical basis at all, and it divides neither a month, a season nor a year evenly, which is why 365 days lands on 52.14 weeks instead of a whole number. It does not start in the same place everywhere either: ISO 8601 puts Monday first, while US calendars and most spreadsheet defaults start on Sunday. That single offset is the usual reason two week-number columns disagree.
