Why are Node.js 20 and Node.js 25 missing?
Today is June 12, 2026, and both dates have already passed: Node.js 20 ended on April 30, 2026, and Node.js 25 ended on June 1, 2026. This page only keeps future timers.
Runtime EOL dates
End-of-life dates tend to sit in release notes until they suddenly become a production upgrade. This calendar is for the supported runtime lines that still have future deadlines after June 2026.
The dates here are fixed vendor support dates, not recurring rules. Node.js 20 and Node.js 25 are left out because their EOL dates have already passed. Each remaining item counts down to the end of the listed support day in UTC.
Use this as a planning calendar for dependency owners, platform teams, and maintainers who need enough lead time for test upgrades, container rebuilds, and rollout windows. Vendor schedules can still change, so evergreen refreshes should re-check the official tables.

Frequently asked questions
Are these dates recurring?
No. Each timer is a concrete vendor support date. The page should be refreshed when the official support tables change, not generated from a recurrence rule.
What does EOL mean for planning?
After end of support, vendors stop publishing normal fixes for that release line. Teams usually plan upgrades earlier so test, deployment, and rollback windows are not squeezed into the final week.
Why use UTC for runtime support dates?
These support tables are global release schedules rather than local civil deadlines. The timers count down to the end of the listed calendar day in UTC.
