day → int?

The day of the month in this date's own calendar, or null if unspecified.

no setter, inherited

no setter, inherited

timezone → String?

The IANA timezone id associated with this date, or null if none.

getter/setter pair, inherited

year → int?

The year in this date's own calendar, or null if unspecified.

no setter, inherited

Methods

adjustRdForTimezone(double rd) → double

inherited

before(int dayOfWeek) → ILibCalendarDate

inherited

calcTimezoneOffset() → void

Resolve and cache tzOffsetDays for the from-UTC-instant path.

inherited

override

getRataDieInstance() → ILibRataDie

The ILibRataDie instance backing this date.

override

getSeconds() → int

The second component (0–59).

override

getTime() → int

The unix time (milliseconds since the epoch) equivalent to this date, or -1 when the instant falls outside the representable range.

inherited

getTimeExtended() → int

The extended unix time equivalent to this date, covering instants outside the range representable by getTime.

inherited

getTimeZone() → String?

The timezone associated with this date as a string, or null if none.

inherited

getWallClockRd() → double

The rata die of this date's wall-clock instant (UTC rata die + tzOffsetDays).

inherited

getWeekOfMonth(String? locale) → int

The ordinal number of the week within the month.

override

getWeekOfYear() → int

The ISO 8601 week number within the current year.

inherited

getYears() → int

inherited

onOrAfter(int dayOfWeek) → ILibCalendarDate

The nearest date on or after this date whose day of week is dayOfWeek.

inherited

onOrBefore(int dayOfWeek) → ILibCalendarDate
