Information about open stores

There are a couple of days in a year almost all stores are closed: on Easter, Thanksgiving and Christmas Day it is common even in the U.S. to find the shops closed. Even in the most liberal country (United Kingdom) Ester and Christmas are sainted days and shops do not open. You cannot know which needs will arise tomorrow. Groceries are missing, you need a drug-store, your computer crashed down and you are search for a new one or looking different items. It is convenient to know, where and when you can pop in right in time and in the span of opening hours. It is a good service to get the most recent information about the shops one would like to visit.
