That would be close - but what about tickets in the previous month, but not resolved (or even still open)? After all, those are tickets we "worked on" during the month in question...
You can also do Ticket searches on "Updated" or "LastUpdated" and "LastContacted" (aka Told) between dates. An "Updated" search will give you any tickets that had Comments or Replies added to them, had custom field changes or status changes.
