No, there are 6 billion people in the world. So the chances of two people being born on the same day are extremely likely. But there is no word for it. It's just, well, not even a covincidence because it's so likely. With 6 billion people in the world, and only 365 days in the year, on average there are more than 16 million people who were born on any particular day.
They are triplets
Two siblings born in the same month and on the same day, but in a different year are simply called 'siblings.' If they both were born on the same month; day and year they would be twins.
There are two syllables. Pres-ence.
