Federal frameworks allow for 107 days of waterfowl hunting. Given that, you can start on a Saturday and close on a Sunday. But, youth days are subtracted from this, leaving 105 days, which would cause a Friday ending date. So, pick your poison.
Could do it like CA does and just throw the last 5 days away and end on a Sunday.
BTW, we don't have a F&G in NV
Its NDOW here.
