The Germanic calendars were the regional calendars used amongst the early Germanic peoples, prior to the adoption of the Julian calendar in the Early Middle Ages.

The Germanic peoples had their own names for the months which varied by region and dialect, which were later replaced with local adaptations of the Roman month names. Our records of Old English and Old High German month names date to the 8th and 9th centuries, respectively. Old Norse month names are attested from the 13th century. Like most pre-modern calendars, the reckoning used in early Germanic culture was likely lunisolar. The Runic calendar developed in medieval Sweden is lunisolar, fixing the beginning of the year at the first full moon after winter solstice.

The month names do not coincide, thus it is not possible to postulate names of a Common Germanic stage, except possibly the name of a spring and a winter month, *austr- and *jehul-. The names of the seasons are also Common Germanic, *sumaraz, *harbistoz, *wentrus, and perhaps *wēr- "spring". The Common Germanic terms for day, month and year were *dagaz, *mēnō-þ- (moon) and *jǣrom. The latter two continue Proto-Indo-European *me(n)ses-, *iero- while *dagaz is a Germanic innovation from a root meaning "to be hot, to burn".

Tacitus in his Germania (ch. 11) gives some indication of how the Germanic peoples of the first century reckoned the days. In contrast to Roman usage, they considered the day to begin at sunset, a system that in the Middle Ages came to be known as the "Florentine reckoning". The same system is also recorded for the Gauls in Caesar's Gallic Wars.

"They assemble, except in the case of a sudden emergency, on certain fixed days, either at new or at full moon; for this they consider the most auspicious season for the transaction of business. Instead of reckoning by days as we do, they reckon by nights, and in this manner fix both their ordinary and their legal appointments. Night they regard as bringing on day."^[1]

The concept of the week, on the other hand, was adopted from the Romans, from about the first century, the various Germanic languages having adopted the Greco-Roman system of naming of the days of the week after the classical planets, inserting loan translations for the names of the planets, substituting the names Germanic gods in a process known as interpretatio germanica.

Month names[link]

The months were probably lunar; the Old English mónaþ, Old Norse mánaðr, and Old High German mánód,^[2] as well as the modern English month, modern Icelandic mánuður, modern Norwegian måned, modern Swedish månad, modern Dutch maand, German Monat and Gothic 𐌼𐌴𐌽𐍉𐌸𐍃, menoþs,^[2][3] are all derivatives of the word moon, with the -th suffix found in words such as depth, width, breadth etc. This connection is also found in several other Indo-European languages.^[3]

Our main source of reference for Old English month names comes from the Venerable Bede. He recorded the pre-Christian Anglo-Saxon month names in his Latin work known as De temporum ratione (De mensibus Anglorum), written in 725.^[4]

Charlemagne (r. 768–814) modified the established Julian Calendar to use the agricultural Old High German names of the months in areas under his influence. (See Julian Calendar: Month names for other examples.) They were used until the 15th century, and persisted in popular or dialectal use into the 19th century.

Icelandic calendar[link]

The old Icelandic calendar is not in official use any more, but some Icelandic holidays and annual feasts are still calculated from it. It has 12 months, broken down into two groups of six often termed "winter months" and "summer months". The calendar is peculiar in that the months always start on the same weekday rather than on the same date. Hence Þorri always started on a Friday sometime between 9 and 15 and January of the Julian calendar, Góa always starts on a Sunday between 8 and 14 February of the Julian calendar.
