⚠️ Common Pitfalls
🚫 Month is a Number
MONTH() returns 10, not "October". Use the TEXT function if you need the month name.
🚫 Text Dates
These functions work best on real Serial Dates. If your date is text ("Oct 31"), they might error out or give unexpected results depending on your system settings.
