IslamicYear Islamic year The collection of all calendar years in the <a href="http://sw.opencyc.org/concept/Mx4rwIbldZwpEbGdrcN5Y29ycA" class="cyc_term">IslamicLunarCalendar</a> system. There are 12 lunar months in the calendar, which means that the months [see <a href="http://sw.opencyc.org/concept/Mx4r1EZROCyJEdaAAABQ2rksLw" class="cyc_term">IslamicMonth</a>] and any events tied to specific days of the year slowly migrate through the seasons from year to year. Islamic years Islamic calendar http://en.wikipedia.org/wiki/Islamic_calendar year CalendarYear A subcollection of <a href="http://sw.opencyc.org/concept/Mx4rvVisWZwpEbGdrcN5Y29ycA" class="cyc_term">Date</a> (q.v.) and an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVijDJwpEbGdrcN5Y29ycA" class="cyc_term">CalendarCoveringType</a> (q.v.). Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvVjyV5wpEbGdrcN5Y29ycA" class="cyc_term">CalendarYear</a> is a year in some particular calendar. Examples include <font color="#ff0000">#$TheYear1972</font> and (<a href="http://sw.opencyc.org/concept/Mx4rvVjympwpEbGdrcN5Y29ycA" class="cyc_term">YearFn</a> 2001). Note that (as with any instance of an instance of calendar-covering-type) a given calendar-year is a temporally-continuous individual that occurs only _once_; e.g. it is not something that recurs each century or each millenium. Pretty String (<a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString IslamicYear Islamic year The collection of all calendar years in the <a href="http://sw.opencyc.org/concept/Mx4rwIbldZwpEbGdrcN5Y29ycA" class="cyc_term">IslamicLunarCalendar</a> system. There are 12 lunar months in the calendar, which means that the months [see <a href="http://sw.opencyc.org/concept/Mx4r1EZROCyJEdaAAABQ2rksLw" class="cyc_term">IslamicMonth</a>] and any events tied to specific days of the year slowly migrate through the seasons from year to year. wikipediaArticleName (<a href="http://sw.opencyc.org/concept/Mx4rTv-jk9SPTXa991kk5mAvHg" class="cyc_term">wikipediaArticleName</a> THING NAME) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article with the title NAME Wikipedia Article Name Wikipedia Article URL (<a href="http://sw.opencyc.org/concept/Mx4rNv0nbm4TTjOp7yhmnzOyqg" class="cyc_term">wikipediaArticleURL</a> THING URL) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article located at URL wikipediaArticleURL CalendarCoveringType type of calendar time interval A specialization of both <a href="http://sw.opencyc.org/concept/Mx4rvgETA5wpEbGdrcN5Y29ycA" class="cyc_term">TemporallyDisjointTemporalObjectType</a> and <a href="http://sw.opencyc.org/concept/Mx4rT2stuKZtEdaAAACgycbRfg" class="cyc_term">TimeParameter</a> (qq.v.), and a collection of collections of time intervals. Each instance COVTYPE of <a href="http://sw.opencyc.org/concept/Mx4rvVijDJwpEbGdrcN5Y29ycA" class="cyc_term">CalendarCoveringType</a> is a collection of <a href="http://sw.opencyc.org/concept/Mx4rvViAw5wpEbGdrcN5Y29ycA" class="cyc_term">TimeInterval</a>s such that the temporally-ordered sequence of all of the instances of COVTYPE would completely cover all of time without any overlap. Thus, <a href="http://sw.opencyc.org/concept/Mx4rvViTO5wpEbGdrcN5Y29ycA" class="cyc_term">CalendarHour</a> is a <a href="http://sw.opencyc.org/concept/Mx4rvVijDJwpEbGdrcN5Y29ycA" class="cyc_term">CalendarCoveringType</a> because all of time consists of a non-overlapping sequence of <a href="http://sw.opencyc.org/concept/Mx4rvViTO5wpEbGdrcN5Y29ycA" class="cyc_term">CalendarHour</a>s. Similarly, <a href="http://sw.opencyc.org/concept/Mx4rvVjAZJwpEbGdrcN5Y29ycA" class="cyc_term">CalendarWeek</a>, <a href="http://sw.opencyc.org/concept/Mx4rvVjeCJwpEbGdrcN5Y29ycA" class="cyc_term">CalendarDay</a>, and <a href="http://sw.opencyc.org/concept/Mx4r0xB65iyJEdaAAABQ2rksLw" class="cyc_term">GregorianMonth</a> are calendar-covering types. Conversely, <a href="http://sw.opencyc.org/concept/Mx4rvVjW85wpEbGdrcN5Y29ycA" class="cyc_term">Monday</a> and <a href="http://sw.opencyc.org/concept/Mx4rvVi4upwpEbGdrcN5Y29ycA" class="cyc_term">December</a> are _not_ calendar-covering types because time does not consist of an unbroken sequence of Mondays, or of Decembers. Also note that a collection called (say) &quot;Week&quot; -- defined (unlike CalendarWeek) as the collection of _all_ seven-day-long periods of time (thus an instance of <a href="http://sw.opencyc.org/concept/Mx4rUZ_j-rTBEdaAAACgycbRfg" class="cyc_term">SameLengthTimeIntervalType</a>) -- would _not_ be an instance of CalendarCoveringType since different Weeks of this sort overlap; e.g. the week beginning today, the week beginning yesterday, and the week beginning tomorrow all overlap. A specialization, in fact the intersection, of <a href="http://sw.opencyc.org/concept/Mx4rthXufFmbQdeHbdGF9gweSw" class="cyc_term">ConventionallyClassifiedTimeIntervalSeries_Disjoint</a> and <a href="http://sw.opencyc.org/concept/Mx4rtadLcFmbQdeca_F8SDbSCQ" class="cyc_term">ConventionallyClassifiedTimeIntervalSeries_Covering</a> (q.v.v.). This collection sounds very much like <a href="http://sw.opencyc.org/concept/Mx4rvVijDJwpEbGdrcN5Y29ycA" class="cyc_term">CalendarCoveringType</a>, but here are the differences. (I) Not all instances of <a href="http://sw.opencyc.org/concept/Mx4rvVijDJwpEbGdrcN5Y29ycA" class="cyc_term">CalendarCoveringType</a> are instances of <a href="http://sw.opencyc.org/concept/Mx4rtdDZwlmbQdeNuckwQ46hMA" class="cyc_term">ConventionallyClassifiedTimeIntervalSeries_CoveringAndDisjoint</a>. The judgment on whether an instance INS of the former is an instance of the latter depends on whether it makes sense in ordinary English to say `the next INS'. For example, `the next year', `the next month', `the next week', `the next day' (tomorrow) etc. make perfect sense in English, perhaps `the next hour' or even `the next minutes' are still okay. It is hard to say whether `the next second' is a member of this collection, but `the next Planck second' or `the next 10^-24 second' should not belong to this collection. (II) Certain interval types not included in <a href="http://sw.opencyc.org/concept/Mx4rvVijDJwpEbGdrcN5Y29ycA" class="cyc_term">CalendarCoveringType</a> may belong to <a href="http://sw.opencyc.org/concept/Mx4rtdDZwlmbQdeNuckwQ46hMA" class="cyc_term">ConventionallyClassifiedTimeIntervalSeries_CoveringAndDisjoint</a>. For example, if we want to talk about `stages' in an long event or a scenerio, or `stages' in a plan, we can have these types of intervals included in <a href="http://sw.opencyc.org/concept/Mx4rtdDZwlmbQdeNuckwQ46hMA" class="cyc_term">ConventionallyClassifiedTimeIntervalSeries_CoveringAndDisjoint</a>. (III) Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvVijDJwpEbGdrcN5Y29ycA" class="cyc_term">CalendarCoveringType</a> must contain intervals that are enough to literally cover the entire time line, while an instance of <a href="http://sw.opencyc.org/concept/Mx4rtdDZwlmbQdeNuckwQ46hMA" class="cyc_term">ConventionallyClassifiedTimeIntervalSeries_CoveringAndDisjoint</a> does not have to have that property. For example, when we talk about `stages' in a scenerio, we don't have to consider the time after the scenerio, and therefore the `stages' do not have be extended to cover the end of time. type of conventionally classified time interval ConventionallyClassifiedTimeIntervalSeries-CoveringAndDisjoint IslamicYear Islamic year The collection of all calendar years in the <a href="http://sw.opencyc.org/concept/Mx4rwIbldZwpEbGdrcN5Y29ycA" class="cyc_term">IslamicLunarCalendar</a> system. There are 12 lunar months in the calendar, which means that the months [see <a href="http://sw.opencyc.org/concept/Mx4r1EZROCyJEdaAAABQ2rksLw" class="cyc_term">IslamicMonth</a>] and any events tied to specific days of the year slowly migrate through the seasons from year to year.
