Happy Birthday Blast
I wanted to try something different with paneling, but also if you're wondering why I mentioned Korea, Korea has a tradition of celebrating collectively the Korean Birthday, eumnyeok saeng-il, which takes place during the Lunar New Year, and everyone gets 1 year older. If you want to find out more, here's an article I found here.
Collective birthdays are also seen in the Polish tradition of imieminy, name day. Because of Catholic roots, many Polish people are named after a saint. Each day of the year is assigned a male saint and a female saint, and you celebrate your name day along with people, who have the same names. For more information, talk to a Polish person, or take a look at this short article.
I'm sure there are other collective birthdays, but the reason I am interested is because out of the numerous amounts of people I have met, I have only met 2 others with the same birthday as me. Now I'm familiar with the calculation of two people having the same birthdays in a group of 23 is around 50%, but what are the chances of those 23 having the same birthday as me?
