Julian calendar

===Eastern Europe===
The calendar month names used in western and northern Europe, in Byzantium, and by the [[Berber calendar#The months|Amazigh (Berbers)]], were derived from the Latin names. However, in eastern Europe older seasonal month names continued to be used into the 19th century, and in some cases are still in use, in many languages, including: [[Belarusian months|Belarusian]], [[Bulgarian months|Bulgarian]], [[Croatian months|Croatian]], [[Czech months|Czech]], Finnish,<ref>{{cite web |url=http://wordinfo.info/unit/3236/ip:23 |title=Calendar, Finnish |website=English-Word Information}}</ref> [[Georgian calendar|Georgian]], [[Lithuanian calendar#Names of the months|Lithuanian]], [[Macedonian months|Macedonian]], [[Polish months|Polish]], [[Romanian calendar#Traditional month names|Romanian]], [[Slovene months|Slovene]], [[Ukrainian months|Ukrainian]]. When the Ottoman Empire adopted the Julian calendar, in the form of the Rumi calendar, the [[Rumi calendar#History|month names]] reflected Ottoman tradition.
