regex

calendar-date

• calendarDate: RegExp matching a calendar-annotated PlainDate string in the RFC 9557 form Temporal writes and reads: the ISO 8601 date, then one [u-ca=<id>] calendar annotation.

calendar-zoned-date-time

• calendarZonedDateTime: RegExp matching a calendar-annotated ZonedDateTime string in the RFC 9557 form Temporal writes and reads — the zoned sibling of calendarDate (regex/calendar-date.ts):

date

• day: RegExp matching an ISO 8601 day of the month: 01–31 (shape only; whether the day exists in its month is checked by Temporal.PlainDate.from in isValidDate).
• month: RegExp matching an ISO 8601 month: 01–12.
• plainDate: RegExp matching ISO 8601 calendar date (extended): YYYY-MM-DD or ±YYYYYY-MM-DD.
• year: RegExp matching the shape of an ISO 8601 year: 4 digits, or a sign and 6 digits (Temporal’s DateYear).

date-time

• plainDateTime: RegExp matching ISO 8601 local date-time (extended): <date>T<time>.

epcis

• epcisEventTime: RegExp matching a GS1 EPCIS 2.0 eventTime (and recordTime): the DateTimeStamp pattern of the EPCIS XSD (https://ref.gs1.org/standards/epcis/epcglobal-epcis-2_0.xsd, a normative artefact of EPCIS 2.0 / ISO/IEC 19987), verbatim and anchored.
• epcisTimeZoneOffset: RegExp matching a GS1 EPCIS 2.0 eventTimeZoneOffset: the pattern the EPCIS JSON schema (https://ref.gs1.org/standards/epcis/epcis-json-schema.json, a normative artefact of EPCIS 2.0 / ISO/IEC 19987) gives for the field, verbatim: ^([+]|[-])((0[0-9]|1[0-3]):([0-5][0-9])|14:00)$.

http-date

• httpDate: RegExp matching RFC 9110 §5.6.7 IMF-fixdate — the only form GMT’s formatHttpDate emits and the preferred HTTP-date form.

leap-second

• instantLeapSecond: RegExp fragment matching an ISO 8601 leap second in every shape Temporal.Instant.from accepts.
• leapSecond: RegExp fragment matching an ISO 8601 leap second (second 60) in the time of day of a date-time or time string, in every spelling Temporal’s PlainDateTime.from/PlainTime.from grammar parses.

nanoseconds

• nanosecondDecimal: RegExp matching the canonical decimal form of a nanosecond timestamp — the shape formatNanoseconds emits and parseNanoseconds accepts.

rfc-2822

• rfc2822DateTime: RegExp matching the strict shape of an RFC 5322 §3.3 date-time (obsoletes RFC 2822): the single-space, case-exact form a generator writes.

rfc-3339

• rfc3339DateTime: RegExp matching an RFC 3339 §5.6 date-time: ISO 8601 with a mandatory offset (Z or ±HH:MM).

sql-date-time

• sqlDateTime: RegExp matching a SQL timestamp literal without a time zone: YYYY-MM-DD HH:MM:SS[.fffffffff].

time

• fractionalSecond: RegExp matching 1–9 fractional-second digits (nanosecond precision).
• hour: RegExp matching an ISO 8601 hour in extended format: 00–23.
• millisecond: Backward-compatible alias for fractionalSecond.
• minute: RegExp matching an ISO 8601 minute: 00–59.
• plainTime: RegExp matching ISO 8601 local time (extended): HH:mm[:ss[.fffffffff]].
• second: RegExp matching a second of 00–59.

time-zone-like

• timeZoneLike: RegExp matching the shape of a time zone identifier: Temporal’s TimeZoneIdentifier grammar (§13.31, the ISO 8601 / RFC 9557 grammar), TimeZoneIdentifier ::: UTCOffset[~SubMinutePrecision] | TimeZoneIANAName.

unix

• unixMilliseconds: RegExp matching a Unix timestamp in milliseconds: exactly 13 digits.
• unixSeconds: RegExp matching a Unix timestamp in seconds: exactly 10 digits.

utc-date-time

• utcDateTime: RegExp matching ISO 8601 UTC datetime: <date>T<time>Z with optional fractional seconds, in ISO 8601 extended format.

utc-offset

• utcOffset: RegExp matching an ISO 8601 UTC offset in the extended form GMT’s offset-instant pair stores: ±HH:MM, optionally ±HH:MM:SS.
