degree conferral vs. attendance date

alexa723

So I graduated from undergrad a semester early. I finished my last classes, finals, etc., in December 2020, however, the conferral date on my diploma is listed as January 31st 2021. Under the education section of some applications it asks for start date, end date, and degree date. Should I list my end date as Dec 2020? Or list both end date and degree date as Jan 2021 as to not be confusing? Other applications ask for dates attended and degree date, so same question for that. Thank you in advance for any insight!
