Selfie Day: is it National or International?

So is this day National or International? Or better to ask: is it only national or also international?
Actually both. As you see: on 21 of June it is National Selfie Day. While right after (on 22 of June) it’s another day for that, and already International.

That’s why annually on 22nd of June it is InternationalĀ Selfie Day!!

National Selfie Day [] was founded by DJ Rick McNeely in 2014

International Selfie Day [] was founded by the team at SelfieElate in 2019
