The Macedonian language has two sets of names of the months of the Gregorian calendar. The most commonly used set of names is derived from the Latin month names and these are used by the vast majority of the Macedonian population. However, there is also a set of older names for the twelve months of Slavic origin that differ from the Latin month names, although their usage is archaized and largely restricted to folk literature and religious calendars issued by the Macedonian Orthodox Church.
The origin of the Macedonian month names is closely related to the agricultural activities that occur in the corresponding period, or to the weather condition common for that period. Some months have alternative names in different regions. The usage of modern Latin month names among Macedonians started towards the end of the 19th century, as a result of mass education.
