<!-- Greece: can anyone add some material that shows what  notation is used in Greece or in Greek to disambiguate a date? (Please do not duplicate the material at [[Adoption of the Gregorian calendar]] but of course it will be essential to summarise it briefly to explain the need for disambiguation, especially since the Church is still using Julian but the state is using Gregorian.  -->

The Gregorian calendar was implemented in Russia on {{nowrap|14 February 1918}} by dropping the [[Julian calendar|Julian]] dates of {{nowrap|1–13 February 1918}},{{efn|The Julian calendar had by that time drifted by another three days since 1582 (in 1700, 1800 and 1900, see [[Century leap year]]) from astronomical reality, so thirteen days needed to be elided.}} pursuant to a [[Sovnarkom]] decree signed {{nowrap|24 January 1918}} (Julian) by [[Vladimir Lenin]]. The decree required that the Julian date was to be written in parentheses after the Gregorian date, until {{nowrap|1 July 1918.<ref name=Grigorenko>[http://grigam.narod.ru/kalend/kalen19.htm История календаря в России и в СССР (Calendar history in Russia and the USSR)] {{Webarchive|url=https://web.archive.org/web/20091017163723/http://grigam.narod.ru/kalend/kalen19.htm |date=17 October 2009 }}, chapter 19 in История календаря и хронология by Селешников (History of the calendar and chronology by Seleschnikov) {{in lang|ru}}.

It is common in English-language publications to use the familiar Old Style or New Style terms to discuss events and personalities in other countries, especially with reference to the [[Russian Empire]] and the very beginning of [[Russian Soviet Federative Socialist Republic|Soviet Russia]]. For example, in the article "The October (November) Revolution", the ''[[Encyclopædia Britannica]]'' uses the format of "25 October (7 November, New Style)" to describe the date of the start of the revolution.{{sfn|EB online|2017}}

===Latin notation: st.v. and st.n.===
The Latin equivalents, which are used in many languages, are, on the one hand, ''stili veteris'' (genitive) or ''stilo vetere'' (ablative), abbreviated ''st.v.'', and meaning {{nowrap|"(of/in) old style"}}; and, on the other, ''stili novi'' or ''stilo novo'', abbreviated ''st.n.'' and meaning {{nowrap|"(of/in) new style".}}<ref name=Lenz210>{{cite book|last=Lenz|first=Rudolf|author2=Uwe Bredehorn |author3=Marek Winiarczyk |title=Abkürzungen aus Personalschriften des XVI. bis XVIII. Jahrhunderts |publisher=Franz Steiner Verlag|year=2002|edition=3|page=210|isbn=3-515-08152-6}}</ref> The Latin abbreviations may be capitalised differently by different users, e.g., ''St.n.'' or ''St.N.'' for ''stili novi''.<ref name=Lenz210/> There are equivalents for these terms in other languages as well, such as the German ''a.St.'' ("''alter Stil''" for O.S.).
