Croatia's rivers belong to the Adriatic and the Black Sea basin. The rivers in the interior are large and calmer (Sava, Drava, Danube).
The unit of currency in Croatia is the Croatian kuna, which was introduced to the newly independent country in 1994, replacing the Yugoslav dinar at a rate of 1 kuna for 1000 dinar. Kuna literally means 'marten', a throwback to earlier times when the currency of the region was animal skins and marten pelts were considered valuable. One kuna is sub-divided into 100 lipa (which means linden tree).
Easter is celebrated with fervor in Catholic Croatia especially in Dalmatia. In some ways it is considered more religious and more serious than Christmas.
