Learn English – A word for “people who were born on the same day from different mothers”

What could be a word for people who are born on the same day but are not siblings?

I am creating a website and matching my college students who were born on same day. I need an appropriate or the closest equivalent word in English to describe that situation. A word or short expression that I could use as its domain name.

I'm not expecting the exact word for this situation, but at the very least it should be an appropriate and acceptable one, even a short phrase will do but its meaning must be comprehensible to visitors to the website.

I need a single word or combination of two words that should be very catchy for the audience.

Can anyone help?
