Finally, in the sources we can (meet with further varieties of both March and ultra-March styles. Their originality lies in the fact that they do not assume as the beginning of the new year a constant number, falling necessarily on March 1. New Year is not firmly established From year to year it fluctuates around March 1, sometimes anticipating this number, but for the most part following it. As the researchers think, these fluctuations are explained by the fact that the New Year's efforts were aimed at coinciding with the first spring full moon. February, or March.
Researchers call a calendar year of March, similar type (with a variable start), circus-March or circus-ultra-March, depending on whether it follows or precedes the January one. The Latin word for "circa" (circa) indicates that New Year's Eve hovers around ("around") March 1st.
It goes without saying that when translating the dates of the circus-March style into modern chronology from the Byzantine era, the rule remains that for events that took place in January and February, the number 5507 is subtracted, and for the period from March to December - 5508. But this the general formula requires one amendment. The number 5508 comes into force as a deduction for translating the dates of events that happened not starting from March 1, but from that date, which in this case is the starting day of the year.
For example, if the year 6646 begins on March 27, then when we transfer this year to our era, for events falling in the period from January 1 to March 26 inclusively, we subtract the number 5507 from 6646, and for events dated from March 27 to December 31 inclusive - 5508.
We apply a similar rule for the ultramart circus year, taking into account the difference between the March and ultra-March styles for 12 months. For events dated according to the circus-ultra-March style, January, February or March, but within the numbers before the beginning of the new year, when converted to modern chronology, 5508 is subtracted, for the rest of the months (after New Year's) through December - 5509. Let's return to the above example with the year 6646, assuming the date is in circus-ultra-March style. If the event occurred during January, February or the first 26 days of March, the number 5508 is subtracted. For the last days of March (from the 27th day), and the following months (April - December), the subtracted number is 5509.
A detailed acquaintance with all the calendar styles discussed above is important when studying sources until the end of the 15th century, when the September account finally comes into force, and moreover, mainly when studying sources of a literary nature, mainly chronicles. As for the ancient Russian acts, dating from the very beginning prevails in the September years. It should also be borne in mind that many of the oldest acts of the XIV-XV centuries. no dates at all.
In the future, we will focus our attention especially on the March and September styles, since from the above it is obvious that the ultra-circus-March systems are only simple versions of the March count. We will leave them aside.

The main question that arises before the researcher, before he begins to translate the date available in the source from the Byzantine era to the modern chronology, is to establish the style used by the source. How can this issue be resolved? I must say right away that this is not an easy task. And you cannot recommend any one recipe that fits all cases. We have to resort to a number of techniques depending on what additional instructions accompany the reference to the year, month, day in the source. Methods for identifying calendar styles used in various sources for dating historical events will be discussed in subsequent sections.
It should also be borne in mind that the translation of dates from the Byzantine era to the modern one takes place according to the Julian calendar, that is, according to the "old style". In order to express the date of the end of the XVI-XVII centuries. according to the Gregorian calendar ("new style"), we must increase it by 10 days. Dates until the end of the 16th century (before 1582), of course, it is impossible to translate into a "new" style: at that time it had not yet been introduced.
