Opens on vs Opens in

Question

I have a service that deals with open hours of businesses.

People can browse the service and see if their favorite business is open right now and if not, when is the next time that it will be open.

If the place is open, we say

Open now.

If the place is closed right now but will open in the next few minutes we say

Opening in 45 minutes.

If the place will open later today we mention the exact time

Opens at 2:00 pm.

And lastly, if for example it's Monday and the place will only be open in Wednesday, we say

Opens in Wednesday at 2:00 pm.

My question is about the last case.

Should it be "Opens in Wednesday at 2:00 pm." or "Opens on Wednesday at 2:00 pm" or perhaps something else ?

Thanks!

The shop doesn't open in Wednesday, but it can open in a specific month (it opens in March) or year (it opened in 2012). For days we use on. — oerkelens, Commented Jun 3, 2015 at 8:53
Or if it regularly opens only on Wednesdays you could say Opens on Wednesdays only. — WS2, Commented Jun 3, 2015 at 9:20

"Opens on", as perhaps you expect. You could just say "Opens Wednesday", possibly, but I don't like the omission much.

The form with "on" omitted is, however, more common—like it or not. books.google.com/ngrams/… (although, oddly enough), the form with "on" is more common with "Sunday"! books.google.com/ngrams/…
