     For the action to pick the date, add a special annotation before specifying the date:
 
     ```md
-    <!-- date-check --> Nov 2025
+    <!-- date-check --> Jul 2026
     ```
 
     Example:
 
     ```md
-    As of <!-- date-check --> Nov 2025, the foo did the bar.
+    As of <!-- date-check --> Jul 2026, the foo did the bar.
     ```
 
     For cases where the date should not be part of the visible rendered output,
     use the following instead:
 
     ```md
-    <!-- date-check: Nov 2025 -->
+    <!-- date-check: Jul 2026 -->
     ```

 <div class="warning">
 rustc's current diagnostics translation infrastructure (as of
-<!-- date-check --> October 2024
+<!-- date-check --> July 2026
 ) unfortunately causes some friction for compiler contributors, and the current
 infrastructure is mostly pending a redesign that better addresses needs of both
 compiler contributors and translation teams.
 Note that there is no current
 active redesign proposals (as of
