Are there any idol birthdays that you celebrate?

Whether it is just dedicating that day to them or participating in the fan projects. Anything. Even wishing them happy birthday on their twitter or insta. Another question could be what is your favorite thing that has happened during an artist's birthday?

For me, I celebrate any of the members of Big Bang, Got7, and Monsta X. I do so by listening to their songs the whole day and wish them hbd on their twitter and Insta. <3

Basically this thread is anything birthday related because today is my birthday! :D

Edit: Thankyou everyone who wished me happy birthday! <3
