Options used for date interval formatting.
Syntax
object {
skeleton?,
date?,
time?,
ca?,
nu?,
context?,
alt?
}
Properties
skeleton: string (DateSkeleton)- Skeleton used to build the interval format pattern
date: string (DateSkeleton)- Skeleton to use when difference between start and end dates is >= 1 day
time: string (DateSkeleton)- Skeleton to use when difference between start and end dates is < 1 day
ca: CalendarType- Override the calendar to use
nu: NumberSystemType- Override the numbering system
context?: ContextType- Specify the context in which the string will be displayed
alt?: DateFormatAltOptions- Specify options for alternate field values.
Defaults
{
context: 'middle-of-text';
}
- If no skeleton is provided, a reasonable default will be automatically selected based on whether the interval is greater- or less-than one day.
- Numbering system default is determined by the locale.
- Calendar system default is determined by the locale.
Example
// June 27, 2018 4:23:00 AM
const epoch = 1530087780000;
const zoneId = 'America/New_York';
const day = 86400000;
const start = { date: epoch, zoneId };
for (const locale of ['en', 'de', 'zh']) {
const cldr = framework.get(locale);
for (const days of [1.2, 3, 17, 73, 1000]) {
const end = { date: epoch + days * day, zoneId };
const result = cldr.Calendars.formatDateInterval(start, end, {
skeleton: 'yMMMMd',
});
log(`${locale} ${result}`);
}
log();

Provide 2 skeletons, one to use if the field of visual difference is greater- or less-than one day:
const cldr = framework.get('en');
// June 27, 2018 4:23:00 AM
const epoch = 1530087780000;
const zoneId = 'America/New_York';
const start = cldr.Calendars.toGregorianDate({ date: epoch, zoneId });
// Two different skeletons to use, if the difference between start
// and end dates is greater or less than one day
const opts = { date: 'EEEyMMMd', time: 'hmsa' };
const fmt = (d: CalendarDate) =>
log(cldr.Calendars.formatDateInterval(start, d, opts));
fmt(start.add({ minute: 1.5 }));
fmt(start.add({ hour: 1.5 }));
fmt(start.add({ hour: 13.5 }));
fmt(start.add({ day: 1.5 }));
fmt(start.add({ week: 1.5 });
fmt(start.add({ month: 1.5 }));
