As you may have guessed, this is a compilation, or a list if you're that kind of person, of people's birthdays. Give me your birthday and you shall be added to my list.
Here talked about my birthday ... Actually I have it the first of June! There was some mistake! It is necessary to fix it as that!
This probably happened because in the U.S. we put the month before the day (it's strange I know) so 1/6/2000 would be read as January 6th 2000, instead of June 1st 2000
In the future, it's probably best to write out the month and day so that it doesn't cause any confusion
