This is just a junk drawer , containing anything used across multiple classes .
Because Luxon is small ( ish ) , this should stay small and we won ' t worry about splitting
it up into , say , parsingUtil . js and basicUtil . js and so on . But they are divided up by feature area .

* This file handles parsing for well - specified formats . Here ' s how it works :
* Two things go into parsing : a regex to match with and an extractor to take apart the groups in the match .
* An extractor is just a function that takes a regex match array and returns a { year : ... , month : ... } object
* parse ( ) does the work of executing the regex and applying the extractor . It takes multiple regex / extractor pairs to try in sequence .
* Extractors can take a "cursor" representing the offset in the match to look at . This makes it easy to combine extractors .
* combineExtractors ( ) does the work of combining them , keeping track of the cursor through multiple extractions .
* Some extractions are super dumb and simpleParse and fromStrings help DRY them .

* A Duration object represents a period of time , like "2 months" or "1 day, 1 hour" . Conceptually , it ' s just a map of units to their quantities , accompanied by some additional configuration and methods for creating , parsing , interrogating , transforming , and formatting them . They can be used on their own or in conjunction with other Luxon types ; for example , you can use { @ link DateTime . plus } to add a Duration object to a DateTime , producing another DateTime .
*
* Here is a brief overview of commonly used methods and getters in Duration :
*
* * * * Creation * * To create a Duration , use { @ link Duration . fromMillis } , { @ link Duration . fromObject } , or { @ link Duration . fromISO } .
* * * * Unit values * * See the { @ link Duration . years } , { @ link Duration . months } , { @ link Duration . weeks } , { @ link Duration . days } , { @ link Duration . hours } , { @ link Duration . minutes } , { @ link Duration . seconds } , { @ link Duration . milliseconds } accessors .
* * * * Configuration * * See { @ link Duration . locale } and { @ link Duration . numberingSystem } accessors .
* * * * Transformation * * To create new Durations out of old ones use { @ link Duration . plus } , { @ link Duration . minus } , { @ link Duration . normalize } , { @ link Duration . set } , { @ link Duration . reconfigure } , { @ link Duration . shiftTo } , and { @ link Duration . negate } .
* * * * Output * * To convert the Duration into other representations , see { @ link Duration . as } , { @ link Duration . toISO } , { @ link Duration . toFormat } , and { @ link Duration . toJSON }
*
* There ' s are more methods documented below . In addition , for more information on subtler topics like internationalization and validity , see the external documentation .

* An Interval object represents a half - open interval of time , where each endpoint is a { @ link DateTime } . Conceptually , it ' s a container for those two endpoints , accompanied by methods for creating , parsing , interrogating , comparing , transforming , and formatting them .
*
* Here is a brief overview of the most commonly used methods and getters in Interval :
*
* * * * Creation * * To create an Interval , use { @ link fromDateTimes } , { @ link after } , { @ link before } , or { @ link fromISO } .
* * * * Accessors * * Use { @ link start } and { @ link end } to get the start and end .
* * * * Interrogation * * To analyze the Interval , use { @ link count } , { @ link length } , { @ link hasSame } , { @ link contains } , { @ link isAfter } , or { @ link isBefore } .
* * * * Transformation * * To create other Intervals out of this one , use { @ link set } , { @ link splitAt } , { @ link splitBy } , { @ link divideEqually } , { @ link merge } , { @ link xor } , { @ link union } , { @ link intersection } , or { @ link difference } .
* * * * Comparison * * To compare this Interval to another one , use { @ link equals } , { @ link overlaps } , { @ link abutsStart } , { @ link abutsEnd } , { @ link engulfs }
* * * * Output * * To convert the Interval into other representations , see { @ link toString } , { @ link toISO } , { @ link toISODate } , { @ link toISOTime } , { @ link toFormat } , and { @ link toDuration } .

* A DateTime is an immutable data structure representing a specific date and time and accompanying methods . It contains class and instance methods for creating , parsing , interrogating , transforming , and formatting them .
*
* A DateTime comprises of :
* * A timestamp . Each DateTime instance refers to a specific millisecond of the Unix epoch .
* * A time zone . Each instance is considered in the context of a specific zone ( by default the local system ' s zone ) .
* * Configuration properties that effect how output strings are formatted , such as ` locale ` , ` numberingSystem ` , and ` outputCalendar ` .
*
* Here is a brief overview of the most commonly used functionality it provides :
*
* * * * Creation * * : To create a DateTime from its components , use one of its factory class methods : { @ link local } , { @ link utc } , and ( most flexibly ) { @ link fromObject } . To create one from a standard string format , use { @ link fromISO } , { @ link fromHTTP } , and { @ link fromRFC2822 } . To create one from a custom string format , use { @ link fromFormat } . To create one from a native JS date , use { @ link fromJSDate } .
* * * * Gregorian calendar and time * * : To examine the Gregorian properties of a DateTime individually ( i . e as opposed to collectively through { @ link toObject } ) , use the { @ link year } , { @ link month } ,
* { @ link day } , { @ link hour } , { @ link minute } , { @ link second } , { @ link millisecond } accessors .
* * * * Week calendar * * : For ISO week calendar attributes , see the { @ link weekYear } , { @ link weekNumber } , and { @ link weekday } accessors .
* * * * Configuration * * See the { @ link locale } and { @ link numberingSystem } accessors .
* * * * Transformation * * : To transform the DateTime into other DateTimes , use { @ link set } , { @ link reconfigure } , { @ link setZone } , { @ link setLocale } , { @ link plus } , { @ link minus } , { @ link endOf } , { @ link startOf } , { @ link toUTC } , and { @ link toLocal } .
* * * * Output * * : To convert the DateTime to other representations , use the { @ link toRelative } , { @ link toRelativeCalendar } , { @ link toJSON } , { @ link toISO } , { @ link toHTTP } , { @ link toObject } , { @ link toRFC2822 } , { @ link toString } , { @ link toLocaleString } , { @ link toFormat } , { @ link toMillis } and { @ link toJSDate } .
*
* There ' s plenty others documented below . In addition , for more information on subtler topics like internationalization , time zones , alternative calendars , validity , and so on , see the external documentation .
