Python 3.10 EOL: Is there an official end-of-support date within October 2026?

Hello team,

I am looking for clarification on the Python 3.10 end-of-life schedule.

The Python Developer Guide currently lists Python 3.10 as reaching end of life in October 2026, and PEP 619 describes the Python 3.10 release schedule. [devguide.python.org]

For planning purposes, I am trying to determine whether there is an official support boundary within October 2026 (for example, a final scheduled date), or whether downstream consumers should simply treat October 2026 as the end-of-support month.

In other words:

  1. Is there an officially planned EOL date for Python 3.10 beyond “October 2026”?
  2. If not, should downstream consumers consider support to end at any point during October 2026 and avoid depending on a specific day?

Thank you for any guidance.

PEP 619 gives a scheduled date, but it’s not in stone and could slip. I would avoid planning around a specific day.

Thanks, Brett. That’s very helpful. For lifecycle and deprecation planning purposes, we’ll anchor on the October 2026 EOL period rather than assuming a fixed day within the month. Appreciate the guidance.
