iso8601
ISO 8601 (and European civil calendar) compliant library of date and time (clock) related predicates. That is, an ISO 8601 handler.
The library supports date representations plus ISO 8601 duration and
interval string conversions using duration_string/2 and
interval_string/2.
An ISO 8601 duration string represents a time amount (e.g. P3D
for three days or P1Y2M3DT4H5M6S for a mixed date/time duration).
An ISO 8601 interval string represents a time interval using two
parts separated by /, where each part can be a date or a duration
(e.g. 2026-02-25/2026-03-01 or 2026-02-25/P3D).
