class for formatting and parsing date intervals in a language-independent man...">DateIntervalFormat</a> will take care of it when creating a date interval formatter when user pass in skeleton and locale.</p> <p>For power users, who want to create their own date interval patterns, or want to re-set date interval patterns, they could do so by directly creating <a class="el" href="classicu_1_1DateIntervalInfo.html" title="DateIntervalInfo is a public class for encapsulating localizable date time interval patterns.">DateIntervalInfo</a> and manipulating it.</p> <p>Logically, the interval patterns are mappings from (skeleton, the_largest_different_calendar_field) to (date_interval_pattern).</p> <p>A skeleton </p><ol> <li> only keeps the field pattern letter and ignores all other parts in a pattern, such as space, punctuations, and string literals. </li> <li> hides the order of fields. </li> <li> <p class="startli">might hide a field's pattern letter length.</p> <p class="interli">For those non-digit calendar fields, the pattern letter length is important, such as MMM, MMMM, and MMMMM; EEE and EEEE, and the field's pattern letter length is honored.</p> <p class="endli">For the digit calendar fields, such as M or MM, d or dd, yy or yyyy, the field pattern length is ignored and the best match, which is defined in date time patterns, will be returned without honor the field pattern letter length in skeleton. </p> </li> </ol> <p>The calendar fields we support for interval formatting are: year, month, date, day-of-week, am-pm, hour, hour-of-day, and minute. Those calendar fields can be defined in the following order: year &gt; month &gt; date &gt; am-pm &gt; hour &gt; minute</p> <p>The largest different calendar fields between 2 calendars is the first different calendar field in above order.</p> <p>For example: the largest different calendar fields between &quot;Jan 10, 2007&quot; and &quot;Feb 20, 2008&quot; is year.</p> <p>There is a set of pre-defined static skeleton strings. There are pre-defined interval patterns for those pre-defined skeletons in locales' resource files. For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is &quot;yMMMd&quot;, in en_US, if the largest different calendar field between date1 and date2 is &quot;year&quot;, the date interval pattern is &quot;MMM d, yyyy - MMM d, yyyy&quot;, such as &quot;Jan 10, 2007 - Jan 10, 2008&quot;. If the largest different calendar field between date1 and date2 is &quot;month&quot;, the date interval pattern is &quot;MMM d - MMM d, yyyy&quot;, such as &quot;Jan 10 - Feb 10, 2007&quot;. If the largest different calendar field between date1 and date2 is &quot;day&quot;, the date interval pattern is &quot;MMM d-d, yyyy&quot;, such as &quot;Jan 10-20, 2007&quot;.</p> <p>For date skeleton, the interval patterns when year, or month, or date is different are defined in resource files. For time skeleton, the interval patterns when am/pm, or hour, or minute is different are defined in resource files.</p> <p>There are 2 dates in interval pattern. For most locales, the first date in an interval pattern is the earlier date. There might be a locale in which the first date in an interval pattern is the later date. We use fallback format for the default order for the locale. For example, if the fallback format is &quot;{0} - {1}&quot;, it means the first date in the interval pattern for this locale is earlier date. If the fallback format is &quot;{1} - {0}&quot;, it means the first date is the later date. For a particular interval pattern, the default order can be overridden by prefixing &quot;latestFirst:&quot; or &quot;earliestFirst:&quot; to the interval pattern. For example, if the fallback format is &quot;{0}-{1}&quot;, but for skeleton &quot;yMMMd&quot;, the interval pattern when day is different is &quot;latestFirst:d-d MMM yy&quot;, it means by default, the first date in interval pattern is the earlier date. But for skeleton &quot;yMMMd&quot;, when day is different, the first date in &quot;d-d MMM yy&quot; is the later date.</p> <p>The recommended way to create a <a class="el" href="classicu_1_1DateIntervalFormat.html" title="DateIntervalFormat is a class for formatting and parsing date intervals in a language-independent man...">DateIntervalFormat</a> object is to pass in the locale.
