I actually don’t really trust business hours on google anymore, I have to go to the restaurant directly or just call since I’ve been burned so many times looking forward to dumplings/teriyaki/pizza and then having the restaurant be closed.

Its a pretty hard problem. Businesses typically only list their opening hours on the door and then those are prone to change without notice. Planned to go somewhere for lunch and needed to check in to a train station in an hour, turns out the lunch place decided today they open half an hour late so I had to quickly rush somewhere else.

If google could deploy that tech demo that calls a business on public holidays to check if they are open, that would be amazing.

This has become an even bigger problem recently, with COVID forcing businesses to suddenly change their hours.

Stores don’t even bother to fix their own signage when they change their hours. You’d pretty much have to crowdsource it.

I usually check the store's site or call. I've had enough entries on Google be wrong to blindly trusy it either.

Store sites tend to be less reliable than Google. Just last night I was searching one and the website had been out of date for months and yet Google had it right.

I've seen that divergence go both ways. Of course, neither source is as reliable as calling (if you get a human to answer), as much of a hassle as calling can sometimes be.

Hmm. At least in the US, Apple Maps gets their business info from Yelp, so it tends to be about as reliable as Yelp is. In general I find Yelp to be mostly on point -- not perfect, but not worse on the whole than Google.

In my experience, I find Google business hours to be more accurate than Yelp. Not sure why, but I think restaurants find Google easier or more important to update when they adjust their hours slightly.
