Oh, Mother's Day is celebrated on the second Sunday in May in Japan as well. Is it the same all over the world?
Haha, though it's very happy that the birthdays go on and on!

I believe it's not the same all over the world, I've already talked to some people from Europe who were surprised when I told them that Mother's Day here was in May and Father's Day in August.

Oh, I see, Father's Day is the third Sunday in June here.
Interesting☺☺
