0.5.0

Breaking changes:

This major update reflects all changes to the Temporal proposal adopted by TC39 between May 2023 and March 2025.

The majority of these changes were made in the June 2024 TC39 meeting (slides here) where the scope of Temporal was reduced at the request of JS engine implementers who were concerned about the size impact of adding Temporal to distributions on limited-capacity devices like low-end Android phones and Apple Watch.

• User-defined calendars have been removed. Calendars are now represented by strings representing built-in calendars. Without custom calendars, the huge surface area of Temporal.Calendar was not necessary, and that type was removed from the proposal.
• User-defined time zones have been removed. Time zones are now only represented by string identifiers representing built-in time zones: either a Zone or Link name from the IANA Time Zone Database, or a time zone offset with minutes precision. Temporal.TimeZone has also been removed, and its methods replaced by the following:
  • getPreviousTransition/getNextTransition - use the new getTimeZoneTransition method of Temporal.ZoneDateTime.
  • equals - use ZonedDateTime.prototype.equals using the same instant and calendar.
  • Other Temporal.TimeZone methods can use the corresponding methods on Temporal.ZonedDateTime.
• Many convenience methods have been removed. In all cases, the same functionality is available using other Temporal methods:
  • Removed getISOFields() methods. Instead use withCalendar('iso8601') and the individual property getters.
  • Removed withPlainDate() methods. Instead use with({ year, monthCode, day }).
  • Removed toPlainDateTime() and toZonedDateTime() methods of Temporal.PlainTime. Instead use the same-named methods on Temporal.PlainDate to combine a date and a time.
  • Removed epochSeconds and epochMicroseconds properties. Instead calculate epoch seconds with Math.floor(epochMilliseconds / 1000) and epoch microseconds with epochNanoseconds / 1000n + ((epochNanoseconds % 1000n) < 0n ? -1n : 0n).
  • Removed toPlainYearMonth() and toPlainMonthDay() methods of Temporal.PlainDateTime and Temporal.ZonedDateTime. Instead use toPlainDate() and then the methods on Temporal.PlainDate.
  • Removed Temporal.Instant.prototype.toZonedDateTime and Temporal.Now.zonedDateTime. Instead use toZonedDateTimeISO()/zonedDateTimeISO() to create a Temporal.ZonedDateTime object using the ISO8601 calendar, and then use withCalendar() if a non-ISO calendar is desired.
• The relativeTo parameter is no longer accepted in Temporal.Duration.prototype.add and subtract. Instead take the relativeTo object, add the two durations to it, and difference it with the original using until().
• Throw if there are multiple calendar annotations in a string and one has the critical flag (Proposal PR)
• Changed the way calculations are done with Temporal.Duration, and placed limits on each of the units. Years, months, and weeks are each limited to 2³²−1. The other units (days through nanoseconds) are collectively limited: taken together, they must be less than Number.MAX_SAFE_INTEGER seconds plus 999,999,999 nanoseconds. This has few user-visible changes, but it does mean that some durations are no longer allowed (for example, Temporal.Duration.from({ seconds: Number.MAX_VALUE }).) (Proposal PR 1, PR 2, PR 3)
• Offset time zones are now limited to minutes precision. That is, you can have [+01:01] but not [+01:00:01] or [+01:00:00.000000001] (Proposal PR)
• For APIs that take a string, other primitives are no longer coerced to strings. Technically, you could previously do Temporal.PlainDate.from(20230711) and it would be treated as Temporal.PlainDate.from("20230711"). This is no longer the case. (Proposal PR)
• Temporal.PlainYearMonth.prototype.toPlainDate and Temporal.PlainMonthDay.prototype.toPlainDate now have clamping behaviour instead of throwing if the resulting PlainDate would be invalid. For example, birthday.toPlainDate({ year: 2025 }) will now return February 28, 2025 if the birthday in question if February 29. (Proposal PR)
  • If you still want the throwing behaviour, you can get it more verbosely:

  const { monthCode, day } = birthday;
  Temporal.PlainDate.from({ year: 2025, monthCode, day }, { overflow: 'reject' });

• Not all calendars have a week numbering scheme, so weekOfYear and yearOfWeek methods may now return undefined (Proposal PR)
• In Temporal.Duration.prototype.round(), rounding to a >1 increment of a calendar smallestUnit while simultaneously balancing to a calendar largestUnit is now disallowed and will throw (Proposal PR)
• Creating a Temporal.MonthDay in a non-ISO8601 calendar will now throw if the year is too far (>¼ million years) in the future or past (Proposal PR)

Bug fixes:

• Fixed several bugs in duration calculations, particularly rounding (Proposal PR 1, PR 2, PR 3, PR 4, PR 5)
• Fixed a bug in start-of-day calculations (Proposal PR)
• Many small bug fixes to bring the polyfill into better compliance with the Temporal proposal

Non-breaking changes

• Many improvements in performance and bundle size
• Remove runtime dependency on tslib. Now this package has only one runtime dependency: JSBI (a polyfill for BigInt)
• Update dev dependencies

A newer version of @​js-temporal/polyfill exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.
