I want to create a custom tshirt design with one of this sentences :
I'm happy today because I was born in Juni 30
I'm so happy because I was born in Juni 30
I want him to wear the shirt on his birthday. But on the other hand, I also want him to keep wearing his shirts on other days. Therefore, I didn't make a sentence like "I am happy today because it is Juni 30" that looks not suitable for wear at other days.
Are these two sentences correct? or do you have any other sentence suggestions for the situation?
