Node.js 26 Ships Temporal API as Stable, No More Date Headaches

Node.js 26 is here, and the headline feature is Temporal, the modern date/time API that replaces Date for anything beyond trivial use cases. After years behind the --experimental-temporal flag, Temporal is now stable and enabled by default.

Temporal: dates done right

import { Temporal } from 'node:temporal'

// Immutable, timezone-aware instant
const now = Temporal.Now.zonedDateTimeISO()
// → 2026-06-12T14:00:00-04:00[America/New_York]

// Add durations without mutation
const nextWeek = now.add({ days: 7 })

// Compare without pain
const isAfter = Temporal.ZonedDateTime.compare(a, b)

// Duration arithmetic that works
const duration = Temporal.Duration.from({ hours: 1, minutes: 30 })
const totalMinutes = duration.total('minutes') // → 90

Key advantages over Date:

• Immutable, all operations return new instances
• Timezone-aware, ZonedDateTime carries IANA timezone, not just offset
• Correct arithmetic, adding a day across DST transitions works correctly
• No more moment, Temporal replaces date libraries for most use cases

What else shipped

• V8 14.6, brings Map.getOrInsert / getOrInsertComputed, Error.isError, RegExp.escape, and Uint8Array base64/hex methods
• Pure JavaScript buffer, the buffer module rewritten in JS, no native dependency
• Intl.NumberFormat v3, expanded formatting options for currencies, units, and compact notation
• Corepack removed, the package manager manager is gone; use npm, pnpm, or yarn directly

Upgrade path

nvm install 26
node --version  # v26.0.0

Node.js 26 is the new LTS release line (even-numbered). Node.js 24 will continue receiving critical fixes but new feature work targets 26.

The bottom line

Temporal going stable is the biggest JavaScript date/time improvement since... ever. If your codebase uses moment, luxon, date-fns, or dayjs, Temporal may replace them for core use cases. Node.js 26 also brings ES2026 features natively, no transpilation needed. If you're starting a new project, start on Node 26.
