That calendar is helpful, but those are decision dates, not application dates. While a majority of schools have a Nov 1 early deadline, many schools have other deadlines. RD application dates vary even more, and there might be different deadlines for scholarships or honors consideration.
I realize it’s not easy, but if this information can somehow be included, it would be super helpful to applicants. Is there a way to scrape this from CC’s EA/ED deadlines page?
