+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.

+The fix is complete. Here's a summary of the change:
+
+**File changed:** `django/db/models/fields/__init__.py`
+
+**Change:** In the `DurationField.default_error_messages['invalid']` string, the format description was corrected from:
+- `[DD] [HH:[MM:]]ss[.uuuuuu]` (incorrect — implied hours were optional but minutes depended on hours)
+
+to:
+- `[DD] [[HH:]MM:]ss[.uuuuuu]` (correct — seconds are mandatory, minutes are optional, and hours are optional only when minutes are provided)
+
+**Rationale:** Looking at the `standard_duration_re` regex in `django/utils/dateparse.py`, the parsing logic is:
+1. `(?P<seconds>\d+)` — seconds are **mandatory**
+2. `(?:(?P<minutes>\d+):)?` — minutes are **optional** (preceding the seconds)
+3. `((?:(?P<hours>\d+):)(?=\d+:\d+))?` — hours are **optional**, but only when followed by both minutes and seconds (the lookahead `(?=\d+:\d+)` enforces this)
+
+So `14:00` parses as 14 minutes and 0 seconds (not 14 hours), which matches the corrected format `[[HH:]MM:]ss`.
