I want to know the answer to the following question:
When did Greece start using the Euro as its currency?
All the background I'm provided with is that "Greece was accepted into the Economic and Monetary Union of the European Union on 19 June 2000, and in January 2001 adopted the Euro as its currency, replacing the Greek drachma at an exchange rate of 340.75 drachma to the Euro.". Is that enough to answer the question?
Answer: yes
