Yes. I didn't mean they sent it out on ivy day, I was just comparing. The day and time was pretty predictable because it's been the same for a couple years now. But there's always a chance, I agree. I hope everyone still waiting gets an interview!No Ivy day is for undergrads which tends to happen at the end of March. Graduate schools don't always follow the same conventions as the undergraduate programs. Grad schools will send out batches of interviews. I'd hate to get your hopes up in case it doesn't work out, but there is still a chance you'll get an interview. So stay positive! I'd wait till the end of the week before you start feeling gloom.
All the best, no matter what
