73-81: Document the date format handlingThe implementation looks good! Consider adding a docstring comment explaining the date format handling, especially for rescheduled dates marked with asterisks.

2-2: Verify python-dateutil dependency
Good choice using dateutil.parser for more flexible date parsing. However, we need to ensure this dependency is properly declared in the project's requirements.
✅ Verification successful
dateutil.parser dependency is properly declared
The dependency is correctly declared in both Pipfile and Pipfile.lock. Additionally, dateutil.parser is already widely used across multiple spiders in the codebase for date parsing, making it a well-established dependency.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check if python-dateutil is declared in requirements files
fd "requirements.*\.txt$" | xargs rg "python-dateutil|dateutil"

76-77: Verify date parsing with various formats
Let's verify that the new date parsing logic handles all expected date formats, including rescheduled dates with apostrophes.
✅ Verification successful
Date parsing implementation is robust and well-tested
The verification shows that:
- The date parsing is well-handled using
dateutil.parser.parse()which is flexible and supports various date formats - The test file includes comprehensive test cases with actual dates (e.g.,
datetime(2018, 1, 23, 9)) - The spider handles date parsing edge cases by:
- Stripping whitespace and splitting on "*" character to handle rescheduled dates
- Setting appropriate default times based on meeting classification (9:00 AM for Board, 1:30 PM for Committee)
- The test suite verifies both regular and cancelled meeting dates

🛠️ Refactor suggestion
Add error handling for date parsing
While using dateutil.parser improves date format handling, we should add error handling to gracefully handle unparseable dates.
- date_str = item.css("td::text").extract_first().strip().split("*")[-1]
- date_obj = dateutil.parser.parse(date_str)
+ date_str = item.css("td::text").extract_first()
+ if not date_str:
+ raise ValueError("No date string found")
+ date_str = date_str.strip().split("*")[-1]
+ try:
+ date_obj = dateutil.parser.parse(date_str)
+ except (ValueError, TypeError) as e:
+ raise ValueError(f"Failed to parse date '{date_str}': {str(e)}")📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Summary
Issue: #N/A
There's an issue with the chi_metro_pier_exposition spyder where it wasn't parsing the date correctly. It wasn't parsing a date with an apostrophe correctly where the apostrophes indicating the dates been rescheduled and wasn't parsing differing date formats.
