/**
|
* Fields and units specific to the ISO-8601 calendar system,
|
* including quarter-of-year and week-based-year.
|
*
|
* This class defines fields and units that are specific to the ISO calendar system.
|
*
|
* ### Quarter of year
|
*
|
* The ISO-8601 standard is based on the standard civic 12 month year.
|
* This is commonly divided into four quarters, often abbreviated as Q1, Q2, Q3 and Q4.
|
*
|
* January, February and March are in Q1.
|
* April, May and June are in Q2.
|
* July, August and September are in Q3.
|
* October, November and December are in Q4.
|
*
|
* The complete date is expressed using three fields:
|
*
|
* * `IsoFields.DAY_OF_QUARTER` - the day within the quarter, from 1 to 90, 91 or 92
|
* * `QUARTER_OF_YEAR` - the week within the week-based-year
|
* * `ChronoField.YEAR` - the standard ISO year (see {@link ChronoField})
|
*
|
* ### Week based years
|
*
|
* The ISO-8601 standard was originally intended as a data interchange format,
|
* defining a string format for dates and times. However, it also defines an
|
* alternate way of expressing the date, based on the concept of week-based-year.
|
*
|
* The date is expressed using three fields:
|
*
|
* * `ChronoField.DAY_OF_WEEK` - the standard field defining the
|
* day-of-week from Monday (1) to Sunday (7) (see {@link ChronoField})
|
* * `WEEK_OF_WEEK_BASED_YEAR` - the week within the week-based-year
|
* * `WEEK_BASED_YEAR` - the week-based-year
|
*
|
* The week-based-year itself is defined relative to the standard ISO proleptic year.
|
* It differs from the standard year in that it always starts on a Monday.
|
*
|
* The first week of a week-based-year is the first Monday-based week of the standard
|
* ISO year that has at least 4 days in the new year.
|
*
|
* * If January 1st is Monday then week 1 starts on January 1st
|
* * If January 1st is Tuesday then week 1 starts on December 31st of the previous standard year
|
* * If January 1st is Wednesday then week 1 starts on December 30th of the previous standard year
|
* * If January 1st is Thursday then week 1 starts on December 29th of the previous standard year
|
* * If January 1st is Friday then week 1 starts on January 4th
|
* * If January 1st is Saturday then week 1 starts on January 3rd
|
* * If January 1st is Sunday then week 1 starts on January 2nd
|
*
|
* There are 52 weeks in most week-based years, however on occasion there are 53 weeks.
|
*
|
* For example:
|
*
|
* * Sunday, 2008-12-28: Week 52 of week-based-year 2008
|
* * Monday, 2008-12-29: Week 1 of week-based-year 2009
|
* * Wednesday, 2008-12-31: Week 1 of week-based-year 2009
|
* * Thursday, 2009-01-01: Week 1 of week-based-year 2009
|
* * Sunday, 2009-01-04: Week 1 of week-based-year 2009
|
* * Monday, 2009-01-05: Week 2 of week-based-year 2009
|
*
|
* @property {TemporalField} DAY_OF_QUARTER The field that represents the day-of-quarter.
|
*
|
* This field allows the day-of-quarter value to be queried and set.
|
* The day-of-quarter has values from 1 to 90 in Q1 of a standard year, from 1 to 91
|
* in Q1 of a leap year, from 1 to 91 in Q2 and from 1 to 92 in Q3 and Q4.
|
*
|
* The day-of-quarter can only be calculated if the day-of-year, month-of-year and year
|
* are available.
|
*
|
* When setting this field, the value is allowed to be partially lenient, taking any
|
* value from 1 to 92. If the quarter has less than 92 days, then day 92, and
|
* potentially day 91, is in the following quarter.
|
*
|
* @property {TemporalField} QUARTER_OF_YEAR The field that represents the quarter-of-year.
|
*
|
* This field allows the quarter-of-year value to be queried and set.
|
* The quarter-of-year has values from 1 to 4.
|
*
|
* The day-of-quarter can only be calculated if the month-of-year is available.
|
*
|
* @property {TemporalField} WEEK_OF_WEEK_BASED_YEAR The field that represents the
|
* week-of-week-based-year.
|
*
|
* This field allows the week of the week-based-year value to be queried and set.
|
*
|
* @property {TemporalField} WEEK_BASED_YEAR The field that represents the week-based-year.
|
*
|
* This field allows the week-based-year value to be queried and set.
|
*
|
* @property {TemporalField} WEEK_BASED_YEARS The unit that represents week-based-years for
|
* the purpose of addition and subtraction.
|
*
|
* This allows a number of week-based-years to be added to, or subtracted from, a date.
|
* The unit is equal to either 52 or 53 weeks.
|
* The estimated duration of a week-based-year is the same as that of a standard ISO
|
* year at 365.2425 days.
|
*
|
* The rules for addition add the number of week-based-years to the existing value
|
* for the week-based-year field. If the resulting week-based-year only has 52 weeks,
|
* then the date will be in week 1 of the following week-based-year.
|
*
|
* @property {TemporalField} QUARTER_YEARS Unit that represents the concept of a quarter-year.
|
* For the ISO calendar system, it is equal to 3 months.
|
* The estimated duration of a quarter-year is one quarter of 365.2425 days.
|
*
|
* @typedef {Object} IsoFields
|
* @type {Object}
