Julian dates are based on a count of the number of days since January 1, BCE “before common era” which is equivalent to BC , plus fraction of a day indicated with decimal numbers. A full day goes from noon to noon, so 6 PM is a quarter of a day, or 0. To calculate a Julian date from a modern calendar date, you simply figure out how many days have passed since BCE, then work out any fractions for a time other than noon. Count the number of years between BCE and your current year.
For example, if the date you’re converting is in , you want the number of years between BCE and CE stands for “common era” and is equivalent to AD. Your total number of years is therefore years.
The Julian Calendar was the system of dating followed from 46BC onwards. Unfortunately, this calculation was not entirely accurate. This may seem a very small amount, but over a large number of years the figure builds up. As a result, it emerged that the Julian Calendar was over-correcting by around 8 days each millennium.

This double-dating is consequential to the different times at which European powers moved from the Julian calendar to the Gregorian calendar. The date of identification used for each treaty in the Consolidated Treaty Series and, by extension, in Oxford Historical Treaties is the date of the signature of the treaty by its negotiators, except where it is otherwise indicated.
This is the customary way to date treaties, and the most practical one, but it is only one of several possible options. The vast majority of the treaties from the period after were made through a multi-phase procedure whereby the treaty text was negotiated, drafted, finalised, and signed by representatives of the principal signatories, and subsequently ratified by those principals.
The multi-phase procedure involved the production of different sets of legal instruments. The first was the text of the agreement signed by the diplomats. The second were the separate documents which attested the ratification by each of the actual treaty parties — the sovereigns — and which were signed and sealed by them.
Treaties normally provided a term within which the signatories would ratify the treaty, which could even vary per party; they did not impose an exact date. By consequence, the ratification by the treaty parties occurred at different moments. Although treaties as a rule only became binding upon ratification by all parties, it is thus more practical to date treaties from the date of signature of the negotiation instrument as this is frequently the only document which is common to all parties.

By Konstantin Bikos and Aparna Kher. The Gregorian calendar was first introduced in , but it took more than years for all the different countries to change from the Julian Calendar. The Gregorian Calendar , also known as the Western or Christian Calendar, is the most widely used calendar in the world today. The Julian formula produced a leap year every four years, which is too many. The Gregorian Calendar uses a much more accurate rule for calculating leap years.
