The criteria for inclusion in the selected anniversaries project pages are subjective due to the fact that any given day of the year can have a great many historical events worthy of listing; relative article quality along with the mix of topics already listed are considered when building OTD sets for each day. Criteria for eligibility are at least:

# The event needs to be of moderate to great historical significance (relative to the other historical events that occurred on the same day of the year). It must be important enough to be included in the selected article (boldfaced item) and should also be the most, or one of the most, important events associated with that article. Furthermore, the event should have occurred on the day in question in the calendar in use at the time (per [[MOS:JG]]).  The date of the event should be determined by the local time, or [[UTC]] if local time is not applicable (e.g., not on Earth).
# Selected articles (boldfaced items) should comply with the criteria for inclusion listed on [[Wikipedia:Days of the year]].
# The selected article (boldfaced item) needs to be updated to clearly state the event or day of the celebration/observance or birth/death, as well as the exact day it occurred/occurs. This is especially true for non-Gregorian-based holidays and observances whose date differs each year. The date ''must'' be [[WP:CITE|cited]] to a [[WP:RS|reliable source]] with an [[WP:CITE#Inline citations|inline citation]], since inline citations are used to support specific statements in an article. The only exceptions are recurring holidays that appear on a given day of the week, such as the first Monday of the month. In those cases, the rule itself must be cited, but the actual date for the current year need not be (see [[WP:CALC]]).
# The selected article (boldfaced item) must ''not'' be a [[Wikipedia:Stub|stub]] and must be [[MOS:BETTER|a relatively complete and well-formatted article]], free from [[Wikipedia:Article message boxes#Categories and colours|'yellow'-level or more severe article issue tags]] (alternatively, many {{tl|citation needed}} tags relative to the article's length may disqualify it in lieu of a banner-sized maintenance tag). In other words, it should be a good example of Wikipedia content (but it does ''not'' need to be a [[WP:good articles|good article]] or a [[WP:featured articles|featured article]]).
# As of February 2017, we now feature at least one birth and death of a notable person, listed underneath the regular blurbs. This number may be increased if space permits. The criteria for inclusion are:
## The article needs to be listed in the '''Births''' or '''Deaths''' section of its corresponding day-of-the-year article (e.g., [[January 1#Births|January&nbsp;1&nbsp;§&nbsp;Births]]), and therefore comply with the criteria for inclusion listed on [[WP:DOY#Births and deaths|WP:DOY&nbsp;§&nbsp;Births and deaths]]. 
## The article is subject to the same quality requirements as those featured in the blurbs.
## People who are listed on their dates of birth may not also be listed on their death dates, and vice versa. Furthermore, if the person is featured (boldfaced item) as a regular blurb on any day, they may not be chosen for birth/death listings (with exceptions, as per below).
# As much as possible, the array of topics should include a variety of years (e.g., not just limited to the 20th/21st centuries), geographical areas (e.g., more than just the [[English-speaking world]]), and subjects (e.g., not too many articles on war or technology).

Ideally, any particular selected article should only be included as a '''boldfaced''' item once in the project pages. To help make sure articles are not selected ('''boldfaced''' item) more than once, [[Wikipedia:What links here|check the links to that article]] and examine all the pages listed that begin with <code>Wikipedia:Selected anniversaries/</code>. There is no limit to the number of times an article can be incidentally linked in the project pages (this includes all the non-boldfaced links). Exceptions can be made when any given day is short for eligible articles and the only suitable article already is featured on a different day. In those cases, those articles still should not be selected more than once in the year (i.e., if an article is eligible for inclusion on multiple days, then it should only make one OTD appearance per year). This rule does not apply to holidays/observances, because the same holiday may be celebrated on different dates in different countries, and country articles, because they may be the boldfaced item for holidays such as an [[List of national independence days|Independence Day]] if the nation's observance doesn't have its own article.

Please note, entries are written in the [[past tense]], preferably in a single sentence.
