Cldr.Time.Interval (Cldr Dates & Times v2.7.0) View Source
Interval formats allow for software to format intervals like "Jan 10-12, 2008" as a shorter and more natural format than "Jan 10, 2008 - Jan 12, 2008". They are designed to take a start and end date, time or datetime plus a formatting pattern and use that information to produce a localized format.

.The available predefined formats that can be applied are the keys of the map returned by
Cldr.DateTime.Format.interval_formats("en", :gregorian)

can be replaced by any configured locale name and:gregorian
is the underlyingCLDR
calendar type.In the case where
from
andto
are equal, a single time is formatted instead of an interval
