In sixth century Europe, the concept of "zero" was still unknown. Thus, the year 1 BC was followed by the year AD 1. Furthermore, modern scholars believe Christ's birth was actually four years earlier than Exiguus thought. In spite of these deficiencies, the dating system devised by Exiguus is now too deeply ensconced in the Western world to easily change.
Perhaps the most unfortunately characteristic of this convention is that "BC" is a suffix used after the year while "AD" is a prefix used before the year. This is inconvenient when generating computerized lists because extra columns must be reserved for both prefixes and suffixes. However, Exiguus' dating system still lacks a "0" year which makes calendrical calculations awkward. The "astronomical" dating system refers to an alternative method of numbering years.
It includes the year "0" and eliminates the need for any prefixes or suffixes by attributing the arithmetic sign to the date. Using this logic, Jesus would have been born either before or after what we use as our year zero, which is meant to signify his date of the birth.
The Gospels also tell us that Christ began his ministry in his 30th year, and that it lasted three years until the Passion. So how do we reconcile this mess? What year are we really in, according to the AD system? This dating controversy fascinated Christian theologians and thinkers throughout the Middle Ages.
In their attempts to reconcile it, the Scythian monk Dionysius Exiguus who died c. But in using this method, Dionysius and Bede both came to find that their version of the annus domini and their placement of the birth of Christ contained errors. In what we would call the year , an Irish monk and chronicler, Marianus Scotus, completed a sprawling chronicle of world history.
Crunching the numbers on all known dated historical events, Marianus demonstrated that Christ was in fact born 22 years earlier than previously acknowledged, meaning that he was writing in what should have been dated AD, not AD. It seems that the accuracy of this dating system was less important than the fact that it existed, and worked as a means of locating dates of past and future events in an intelligible framework.
So, how do we know what year we are in? Clearly, we are in whatever year we say we are, according to whatever dating system we choose to use. And who knows what measures may be deemed more applicable to future generations.
It is the calendar used in the international standard for Representation of dates and times: ISO It is a solar calendar based on a day common year divided into 12 months of irregular lengths. However, nearly every four years is a leap year , when one extra — or intercalary — day, is added on 29 February , making the leap year in the Gregorian calendar days long. The days of the year in the Gregorian calendar are divided into 7-day weeks , and the weeks are numbered 1 to 52 or The international standard is to start the week on Monday.
However, several countries, including the US and Canada, count Sunday as the first day of the week. The Gregorian calendar's predecessor, the Julian Calendar , was replaced because it was too inaccurate.
It did not properly reflect the actual time it takes the Earth to orbit once around the Sun, known as a tropical year. The Julian calendar's formula to calculate leap years produced a leap year every four years. This is too often, and eventually, the Julian calendar was several days out of sync with the fixed dates for astronomical events like equinoxes and solstices.
The introduction of the Gregorian calendar allowed for the realignment with events like the vernal equinox and winter solstice. The Gregorian calendar was first adopted in Italy, Poland, Portugal, and Spain in , and included the following changes:. In Europe's Protestant countries, however, people feared that the new calendar was an attempt by the Catholic Church to silence their movement. Modern Tactical Knives. Native American Tools.

This method is to ensure that the right pictures get put in the right posts.
Also, some of the knives are "temporarily misplaced", hiding in the wrong tubs. One of my favorite knives of all time is the Western W49 Bowie Knife and its variations. I have identified multiple variations of the W49 with the earliest dating back to WW2.
I am certain that there are variations that I have not even encountered yet. Any dates I have assigned to a variant are based on the best information I have at this time, as gleaned from books, advertisements, anecdotal evidence stories and SWAGs. Due to the manner in which Western catalogs were promulgated, exact dates for some versions have been elusively difficult to nail down.
In the case of a dual year designation, e. Obviously, the year code versions are a piece of cake. Many times, dates are based on when someone says they bought Version X. A reported date of purchase along with a receipt can be used to move the initial use date of a stamp backwards in time, but such evidence can never definitively indicate when the use of a particular stamp ended.
What really happens is that some user or collector happens to notice that a change has occurred. Just remember, some of the info I have is set in concrete, while other info is set in Jello.

The guard is a stamped steel oval, unlike the large brass guard with quillions found on the original bailout machete, the Legitimus Collins 18 and the Case copy of the There are two small fuller grooves on each side. I'm not certain if Cole decided to name them V44 that or if he was just following along with the prevailing nomenclature.
V44 was a Case in-house designation of the fixed blade machete. Both the V44 designation and the Marine Raider Bowie designation are fodder for a separate discussion threads. The ONLY differences between versions 2, 3 and 4 are in stamp location s. Western Bowie 2 — Western Bowie, version 1 - Time frame -- ?
W49 was only used in-house as a stock number. The handle materials are rosewood and the butt is smoothly rounded. The sheaths for these first Western Bowies were dangler-less. Generally, the initial date for the Western Bowie is taken as gospel to be This is usually based on an advertisement showing an Army Sargent holding one.
Possible explanations are: 1 — Someone back-dated a presentation plaque when it was finally made some time after There are no ricasso stamps. The stamps are on either side of the guard instead. The early sheaths for this version did not have a dangler, but anecdotal testimony via Sactroop where 3 individuals known to Sactroop indicate that the knives they purchased in early came with the dangler sheath.
This is probably an indication of advertising lagging reality. The early dangler sheaths may be identified by looking at the pair of rivets on the back of the sheath. Early sheaths have solid rivets. At some point, someone at Western determined that the thigh strap grommet would work in place of the rivets just as well and Western would only have to maintain 1 item in stock.
Beginning with this version, the three rivets are the large ones used by Western, Coleman and Camillus. It is unknown how long the S was actually made. The date on my S just means that they were still available for sale in NIB.
