No such date

error An error stops the build: nothing is published until it is fixed.

A date is written in the right form, but the calendar has no such day: 30 February, month 13, a time such as 25:70, or an offset more than 14 hours from UTC.

What you’ll see

error  No such date: there is no 30 February in 2026
  More: https://statac.dev/e/no-such-date/

In the terminal the message also names the file and line where there is one, and marks the exact text.

Why Statac stops

Statac can’t tell which day you meant, and choosing the nearest real one could put a post on the wrong day.

How to fix it

Correct the date. The message names the part that doesn’t exist.

Example

In content/post-1.md:

---
title: Post 1
date: 2026-02-30
---

February 2026 has 28 days:

---
title: Post 1
date: 2026-02-28
