I think Ryan just wanted some 2017 dates in his dataset. As Order date only went up to 2016, he just added an extra 365 days so that 2017 is available for him to use.
Maybe when he wrote that blog it happened to be 2017?
Hi Mavis -
I am not sure how that would affect the time period I was trying to query for. I was querying 9/1/2016 to 9/30/2016. Not sure if the period selection is 2016, why he would incorporate a 2017 logic in it.
