This is clearly written in the TC's :
"If I check-in before January 1, 2018 or check-out after April 30, 2018, do I still earn credit for that stay?
Registered Hilton Honors members will receive a bonus only for the nights of an
eligible stay completed during the Promotion Period, regardless of a check-in date before the Promotion Period begins or a check-out date after the Promotion Period ends."
I would think that as long as your stay bridges the start or end date, it still counts as a stay. Note above it says nights during the period counts which would hence be part of the stay.
