What is open on christmas day 2015?

As an AI language model, my training data only goes up to the year 2021 and I don't have access to current events and information. However, I can provide some general information about Christmas Day openings.

In many countries, Christmas Day is a public holiday, which means that most businesses, including stores, restaurants, and other establishments are closed. However, in areas where Christmas is not widely celebrated or in emergency services, some businesses may remain open.

In recent years there has been a trend towards some large stores and chains opening on Christmas Day for a limited time, often with reduced hours. This is because there is a growing market for people looking to get out of the house and find something to do outside of their homes on Christmas Day, or those who may not celebrate the holiday and are looking for places to go.

It's important to note that the decision to open on Christmas Day is often left up to individual businesses, so it's best to check with specific establishments to see if they will be open.
