There closed
If they are not open, then they are closed. If they are closed it is time for them to be closed or something has happened for them to close.
They open at 10:30 am and close at 1:00 am (1:30 am Friday and Saturday.)
In-n-out was never 24 hour. I believe they are 10:30am til 11:00 am,or maybe i bit later on weekends
Their 24/7
Most likely no one is working. Check the hours of operation.
They are open for specific parts of the day.
