+Goal: Correct expected format in invalid DurationField error message
+Description
+	
+If you enter a duration "14:00" into a duration field, it translates to "00:14:00" which is 14 minutes.
+The current error message for invalid DurationField says that this should be the format of durations: "[DD] [HH:[MM:]]ss[.uuuuuu]". But according to the actual behaviour, it should be: "[DD] [[HH:]MM:]ss[.uuuuuu]", because seconds are mandatory, minutes are optional, and hours are optional if minutes are provided.
+This seems to be a mistake in all Django versions that support the DurationField.
+Also the duration fields could have a default help_text with the requested format, because the syntax is not self-explanatory.

+Perfect! Now let me create a final summary of what was accomplished:
+
+## Summary
+
+I have successfully fixed the Django issue regarding the incorrect DurationField error message format. Here's what was done:
+
+### Problem
+The error message for invalid DurationField values specified an incorrect format:
+- **Old (incorrect)**: `[DD] [HH:[MM:]]ss[.uuuuuu]`
+- **Correct**: `[DD] [[HH:]MM:]ss[.uuuuuu]`
+
+The old format suggested that hours and minutes were both optional in the same way, but the actual parsing behavior requires:
+- Seconds are **mandatory**
+- Minutes are **optional** 
+- Hours are **optional** but if provided, must be followed by minutes
+
+### Examples validating the fix
+- `"14:00"` → parses to `0:14:00` (14 minutes)
+- `"01:30"` → parses to `0:01:30` (1 minute 30 seconds)  
+- `"120"` → parses to `0:02:00` (120 seconds)
+- `"1:02:03"` → parses to `1:02:03` (1 hour 2 minutes 3 seconds)
+- `"1 01:02:03"` → parses to `1 day, 1:02:03`
+
+### Changes Made
+The fix involved updating 91 files:
+1. **Main source code** (`django/db/models/fields/__init__.py`): Updated the error message
+2. **Test file** (`tests/model_fields/test_durationfield.py`): Updated test expectations
+3. **All locale files** (89 `.po` files in `django/conf/locale/`): Updated translated format strings
+
+### Testing
+- All DurationField model tests pass ✅
+- All DurationField form tests pass ✅  
+- All duration parsing utility tests pass ✅
+- Confirmed the error message now displays the correct format ✅
+
+### Commit
+The changes have been committed with the hash `d332abee97` with a comprehensive commit message explaining:
+- The issue and the fix
+- The reasoning based on the actual `parse_duration()` regex pattern
+- Examples of valid inputs demonstrating the correct behavior
