Arguments

from is any map that conforms to the Calendar.datetime type.
to is any map that conforms to the Calendar.datetime type. to must occur on or after from.

The available predefined formats that can be applied are the keys of the map returned by Cldr.DateTime.Format.interval_formats("en", :gregorian) where "en" can be replaced by any configuration locale name and :gregorian is the underlying CLDR calendar type.
In the case where from and to are equal, a single date is formatted instead of an interval
