isValidDateTime

Signature

isValidDateTime(value: string): boolean

Return true when value is a valid PlainDateTime string.

• The part before the first annotation must match plainDateTime.
• Reads RFC 9557 annotations as Temporal.PlainDateTime.from does: elective ones ([foo=bar]) and a time zone annotation are ignored, and an unknown critical one ([!foo=bar]) is rejected. The calendar must be ISO ([u-ca=iso8601] is accepted).
• Rejects leap seconds (e.g., “2024-02-29T23:59:60”).
• Rejects invalid dates (e.g., “2024-02-30”) and invalid times (e.g., “2024-02-29T24:00:00”).
