Grep lines that cotain "1111-11-11" or "2382-21-20". (Any Numbers)

I have tried to do this and I came up with this

grep -E '\<[0-9]{4}"-"[0-9]{2}"-"[0-9]{2}\>'

It doesn't work and the reason for that is the "-" and multiple grep things, so I tried dividing them with a pipe like this

grep -E '\<[0-9]{4}-|[0-9]{2}-|[0-9]{2}\>'

But it still matches lines like 4444, or similar. Anyone know how to achieve what I want?
