What day is February 30th?

It’s the day of my engagement. I’ve told my friends. The text message is as follows.

I am already going through the procedures for dropping out of school and taking the exam. I'm depressed, and I'm planning to get engaged. I'm going to do it on February 30th. The reason is very complicated, it's too sudden, my parents made the decision, don't reply to me, I'm in a bad mood, I'm depressed!!

I know. Are you done?^$^
