If I cancel my ED extension of stay, can I leave Thailand a day earlier than the cancellation date?

You can leave Thailand a day earlier than the cancellation date of your ED extension of stay. Generally, immigration offices allow individuals to leave up to a week early, as long as you provide documentation from your school confirming your last day of study. Upon cancellation, you'll receive a stamp that allows you to remain in the country until the date specified, which means you can leave any time before that date, including a day earlier.
