Denmark did not leave the EU. It is still a member. It does not use the Euro, but that does not mean it is not in the EU. Some other EU countries do not use the Euro. Only 19 of the 28 member countries use it.
Actually, all countries that use the euro are part of the European Union (EU), as the euro is the official currency of EU member states. However, there are countries like Kosovo and Montenegro that use the euro without being EU members. These countries have unilaterally adopted the euro for practical reasons, but they do not have the same rights and obligations as EU member states. Thus, while all eurozone countries are EU members, some regions or territories may use the euro outside of EU membership.
As of the 1st of January 2014, 18 of the European Union's 28 countries use the euro.
Montenegro and Kosovo are countries that are not in the EU but use the Euro (Kosovo also uses the Serbian Dinar)
The currency is called the Euro, not the Euro Dollar. Not all countries in the European Union use the Euro. There are 28 countries that are members of the European Union. 18 use the Euro. 10 use their own currencies.
