How to specify a day and a shop/office/etc. when asking for business hours?


I'm very sorry this is a very basic Question, I just started learning japanese
as my third language (german being my native one and english my second) and
Right now I learned a basic way of asking for Business Hours, what time it is
Right now etc.

But I came across something I couldn't find explained: I can ask "When does
the postoffice close" or "When does it (which was mentioned beforehand so I
don't have to repeat it here) close tomorrow" But I can't put both in one
sentence like "When does the postoffice close tomorrow" I hope you get what I
mean? With my very limited Knowledge Right now I would Need to put two
particles to mark the subject of my sentence, which I can't do as far as I'm
concerned.

I'm grateful for every help or someone who can tell me where this has already
been answered.




Perhaps an easier way to ask for this information could be:

> 明日{あす}の **営業時間{えいぎょうじかん}** は何時{なんじ}ですか？

営業時間 means the "operating hours" and is a very common way _(especially on the
phone)_ to ask when a business or office will be open or closed.

Normally the response will be something like:

  * 朝{あさ}[10時]{じゅうじ}から[5時半]{ごじはん}です

So now you would know when the place opens and when it closes.
