Methods
`checkDate`	Source Code`shared actual void checkDate(Integer[3]Go to Tuple abbreviation [X,Y] means Tuple<X\|Y,X,Tuple<Y,Y,[]>> date)` Assert that specified date has it conjunction of year, month and day as valid gregorian values. Parameters: `date` Invalid year value Invalid date value Refines `Chronology.checkDate`
`dateFrom`	Source Code `shared actual Integer[3]Go to Tuple abbreviation [X,Y] means Tuple<X\|Y,X,Tuple<Y,Y,[]>> dateFrom(Integer date)` Converts the fixed date value to an equivalent gregorian date. Refines `Chronology.dateFrom`
`dayFrom`	Source Code `shared Integer dayFrom(Integer date)` Returns day of month value of the fixed date value.
`dayOfWeekFrom`	Source Code `shared Integer dayOfWeekFrom(Integer date)` Returns day of week value for the specified fixed date value.
`fixedFrom`	Source Code `shared actual Integer fixedFrom(Integer[3]Go to Tuple abbreviation [X,Y] means Tuple<X\|Y,X,Tuple<Y,Y,[]>> date)` Return the day of era from a given date. Refines `Chronology.fixedFrom`
`leapYear`	Source Code `shared actual Boolean leapYear(Integer year)` Gregorian leap year rule states that every fourth year is a leap year except century years not divisible by 400. Refines `LeapYear.leapYear`
`monthFrom`	Source Code `shared Integer monthFrom(Integer date)` Returns the month number of the gregorian calendar from the fixed date value.
`newYear`	Source Code `shared Integer newYear(Integer year)` Returns fixed date value of the first day of the gregorian year.
