Call for the hours on that day
Call and ask for hours. At best they'd closed a few hours before 10.
Thanks for the update
Google automatically says that hours may differ on holidays - Walmart has no control over what Google shows in search results. most of the stores closing early are location-specific. all of the stores hours I've looked at online are normal store hours, but that doesn't mean store management hasn't elected to reduce hours, so I would call in the morning to be sure.
