{{Wikipedia subcat guideline|naming conventions|Numbers and dates}}
Wikipedia:Manual_of_Style_(dates_and_numbers) gives the general principles of how Wikipedia deals with the representation of numbers and dates.
This present naming conventions guideline concentrates on the aspect of how numbers and dates are represented in ''article titles'', that is the names of the articles where the content is (as opposed to redirect pages that also allow non-standardized article titles).
The approach of this guideline is listing recommendations by article content type.
==Articles on years, articles on numbers, article names containing non-date numbers==
By convention, an article name that is a number (in Arabic_numerals) represents a ''year''{{ref|year}}. Such articles give an overview, in the form of a list, of the major events that took place (or are planned to take place) in that year. In general the use of number-only page names should only be used for "Year in Review" entries.
For years BC, the format is " BC", for example 44_BC.
So, if some numbers, that don't indicate a year, have a specific meaning, an additional qualifier or disambiguation technique is needed:
* for articles on a ''number'' as such, the bracketed qualifier (number) is added, e.g. 3_(number)
* Other:
** 36_(film), not 36 (the year Pontius_Pilate was called back to Rome);
** Intel_80386, not 386 (the year the Northern_Wei_Dynasty began to rule China);
** Form_1040, not 1040 (the year Macbeth became King of Scotland);
** ''Nineteen_Eighty-Four'' for the George_Orwell novel, not 1984 (the year Marvin_Gaye died).
Nonetheless some numbers above a normal date range have another topic than a year, e.g. 4711.
Note that numbers in Roman_numerals are usually pages that redirect to:
* the related ''number'' article for ''lower'' numbers, e.g. VII redirects to 7_(number)
* the related ''year'' article for ''higher'' numbers, e.g. MMVI redirects to 2006
Unless, of course, the letters, not read as Roman numerals, compose a word with another meaning, e.g. MIX.
There is a unicode range of characters that is specifically used for Roman numerals, for example "Ⅰ" (0x2160) and "ⅰ" (0x2170) - such (individual) characters are redirect pages to the corresponding ''number'' page: for instance both "Ⅰ" (0x2160) and "ⅰ" (0x2170) redirect to 1_(number). For other uses it is discouraged to use these characters in wikipedia article page names. Note also that no automatic case conversion to upper case takes place when these characters are used as the first character of a wikipedia page name (in other words: "Ⅰ" and "ⅰ" are two ''different'' redirect pages).

==Articles on other standard time periods==
===Days===
* All days of a year cycle have an article in the format " ", e.g. February 27 February_27 which displays as February_27, depending on your date preferences.
* Additionally, days from some recent years (currently: 2003–2005) have an article with a title in the format " , ", e.g. February_27,_2003 - these articles on a specific day of a specific year can be reached from the " " articles via the {{tl|ThisDateInRecentYears}} template. With the parameters Month=February and Day=27, this template shows as follows:
{| Align = "center"
|-
| Align="center" | {{ThisDateInRecentYears|Month=February|Day=27}}
|}
* Of course there are also the articles Monday to Sunday, without numbers in the article name.
===Decades===
* Format: "s( BC)", e.g. 1970s, 40s_BC (see: Category:Years_by_decade)
===Centuries===
* Format: "''th'' century( BC)", e.g. 3rd_century_BC (see: Category:Centuries)
===Millennia===
* Format: "''th'' millennium( BC)", e.g. 2nd_millennium (see Category:Millennia)
==Articles on events==
===Events recurring at regular intervals===
There are many events that repeat on a regular or semi-regular basis, such as the Summer Olympics or the U.S. presidential elections. For important events, we will want a separate article for every time the event was held. For such events, one question that arises is: "What's the best way to disambiguate this series of articles?".
====Bracketed disambiguator style====
A format for separate articles on events that recur at ''regular'' intervals is as follows:''' is the existing article title (non-redirect) that describes the event;
*'''
'''Where: *'''(
