I have witnessed the celebration of international days but some in this list is funny and not worth celebrating...

This should be an off topic unless dogs have roles they play in bitcoin. I won't be surprised to see happy international cat day.

I don't know that Bitcoin whitepaper day is celebrated. There should also be bitcoin first block day celebration.

I don't understand this one at all. Is it a national victory?

Happy sisters day, happy cousins day, happy uncles day lol.

I don't blame Xal0lex because his intention was pure, just that people try to abuse every thing they can. If you observe very well, you will understand he didn't merit all of those celebrations. He merited only those that are worth it.
