# Slavic calendar

While many Slavic languages officially use Latin-derived names for the months of the year in the Gregorian calendar, there is also a set of older names for the twelve months that differs from the Latin month names, as they are of Slavic origin. In some languages, such as the Serbian language these traditional names have since been archaized and are thus seldom used.
The original names of the months of the year in the Slavic languages closely follow natural occurrences such as weather patterns and conditions common for that period, as well as agricultural activities.
Many months have several alternative names in different regions; conversely, a single "Slavic name" may correspond to different "Roman names" (for different months, usually following each other) in different languages.

## Comparison table

The Slavic names of the months have been preserved by a number of Slavic people in a variety of languages. The conventional month names in some of these languages are mixed, including names which show the influence of the Germanic calendar (particularly Slovene, Sorbian, and Polabian) or names which are borrowed from the Gregorian calendar (particularly Polish and Kashubian), but they have been included here nonetheless.
In Latvian and Lithuanian, the Baltic names of the months are preserved, which partially coincide with the Slavic ones, which suggests that some of these names may date back to the time of Balto-Slavic linguistic unity. Latvian and Lithuanian names are also shown in this table for comparison.
Words are colored according to etymology.

## Croatian months

The Croatian months used with the Gregorian calendar by Croats differ from the original Latin month names. While subject to variation over the earlier centuries, their names and order have been standardised in 1830s through the efforts of the Illyrian movement and its chief linguist Vjekoslav Babukić.
| No. | Latin name | English name | Croatian name | Etymology |
| 1 | Ianuarius | January | sijȇčanj | from cutting or hewing wood but there are also dialectal terms svečan, svičen, sičan that have a meaning 'festive', so there is a possibility of a meaning 'festive month' (as there are several holidays celebrated in January) |
| 2 | Februarius | February | vèljača | month in which days become longer, oveljiti se = to get bigger; or to wallow, to roll valjati, to indicate unstable weather |

## Czech months

The names of Czech months are, as in Belarusian, Croatian, Kashubian, Polish, and Ukrainian, not based on the Latin names used in most European languages. The suffix -en is added to most of the months' names.
| No. | Latin name | English name | Czech name | Etymology |
| 1. | Ianuarius | January | leden | From led, "ice". |
| 2. | Februarius | February | únor | Probably from the word root -nor-, infinitive form nořit (se), "to plunge, to welter", as the ice welters under the lake surface. |

| 5. | Maius | May | květen | From květ, "blossom". Originally máj, "May". The word květen first appeared in Jungmann's translation of Atala from 1805 as a poetism and translation for French lune de fleurs (month of flowers), but quickly gained acceptance. Jungmann was probably also influenced by the Polish word kwiecień ("April"). |
| 6. | Iunius | June | červen | Either from červený, "red", or from červ, "worm", both related to fruit. |
| 7. | Iulius | July | červenec | The same as červen with a diminutive suffix ec, lit. "small červen". |

| 11. | November | November | listopad | Literally "leaf-fall". |
| 12. | December | December | prosinec | Either from prosit, "to pray, beg, to ask, to plead", possibly relating to holidays at this time, or from prosinalý, "pallid", from siný, deep blue, because the sky is usually pallid at this time. |

## Macedonian months

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 conditions 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.
