We believe that the numeric notational marks associated with the animals constituted a calendar, and given that it references natural behaviour in terms of seasons relative to a fixed point in time, we may refer to it as a phenological calendar, with a meteorological basis.

relative to bonne saison or RBS

The obvious event is the so-called ‘bonne saison’, a French zooarchaeological term for the time at the end of winter when rivers unfreeze, the snow melts, and the landscape begins to green. This of course varies by several weeks from the south to the north of Europe, but corresponds approximately to late spring. We hypothesize that spring, therefore, with its obvious signals of the end of winter and corresponding faunal migrations to breeding grounds, would have provided an obvious, if regionally differing, point of origin for the lunar calendar.

The intercalary month or epagomenal days[1] of the ancient Egyptian, Coptic, and Ethiopian calendars are a period of five days in common years and six days in leap years in addition to those calendars' 12 standard months, sometimes reckoned as their thirteenth month. They originated as a periodic measure to ensure that the heliacal rising of Sirius would occur in the 12th month of the Egyptian lunar calendar but became a regular feature of the civil calendar and its descendants. Coptic and Ethiopian leap days occur in the year preceding Julian and Gregorian leap years.

Jungius beschäftigte sich lange mit verschiedenen Kalendersystemen. In seinen Briefen kann man sehen, welche Probleme es damals bereitete, dass einige Gebiete dem Gregorianischen Kalender folgten und andere, darunter auch Hamburg, noch dem Julianischen.

In 1991, the earliest known roundel was found in Germany, also corresponding to the Stroked Pottery culture. Called the Goseck Circle, it is 246 feet (75 m) in diameter and had a double wooden palisade and three entrances. Because two of the entrances correspond with sunrise and sunset during the winter and summer solstices, one interpretation of the Goseck Circle is that it functioned as an observatory or calendar of sorts, according to a 2012 study in the journal Archaeological Papers of the American Anthropological Association (opens in new tab).

The two corresponding dates should be given in case ofOld Style and New Style; of French Revolutionary andGregorian calendars; of Mohammedan and Christian eras;etc. Aid in dealing with these problcms may be convenientlyobtained from John J. Bond, ZIandy book of rules and tablesfor verifying dates rhth the Christian era, 4th cd., London,1889. and other treatises on chronology.

the first precision-geared mechanism known is a relatively simple—yet impressive for the time—geared sundial and calendar of Byzantine origin dating to about C.E. 600.

By contrast, the 364-day calendar was perfect,” they write in the Journal of Biblical Literature. “Because this number can be divided into four and seven, special occasions always fall on the same day. This avoids the need to decide, for example, what happens when a particular occasion falls on the Sabbath, as often happens in the lunar calendar. The Qumran calendar is unchanging, and it appears to have embodied the beliefs of the members of this community regarding perfection and holiness.”

Ratson and Ben-Dov found that the scroll lays out the most important dates in the Qumran sect’s 364-day calendar, including the festivals of New Wine and New Oil, which are not mentioned in the Bible. It also reveals for the first time the name given to the special days on which the sect would celebrate the transition between seasons, four times a year. The days were referred to as “Tekufah”, which translates as “period”.
