XSD Date/Time

This lesson is part of XML · All levels

Summary

XML Schema has specific date and time types: xs:date, xs:time, xs:dateTime, xs:duration, as well as xs:gYear and its derivatives. The writing must comply with ISO 8601, e.g. 2026-10-23 for the date and 2026-10-23T09:30:00 for the dateTime. The time limit is set with the minInclusive and maxInclusive facets, while the time zone is written with the Z-shaped or offset +07:00.
