A further complication is that for a long time the year in England began on 25 March (Lady Day), so for example Elizabeth I of England was recorded as having died on 24 March1602 (Old Style); this would be written 24 March1603 in the modern system of numbering years, which corresponds to 3 April1603 (New Style). For complete avoidance of ambiguity, historians write dates in the ambiguous part of the year in slashed format, for example "24 March/3 April 1602/1603".
In Russia, the terms "Old Style" and "New Style" have exactly the same meaning, the only difference being that Gregorian calendar have been introduced there much later — on February 14, 1918 (New Style).
Accordingly, when the new calendar was put in use, the error accumulated in the thirteen centuries since the Council of Nicaea was corrected by a deletion of ten days.
People have avoided changing historical records in Britain deriving from this period; however, it is often highly desirable to translate particular Old Style dates into their NewStyle equivalents, such as where the context includes reference to other countries that had already converted to NewStyle before Britain did.
Dates of events in Great Britain prior to 1752 are usually now shown in their original Old Style form, whereas dates of events in (then British) America prior to 1752 are usually now shown in the NewStyle form.
