Yesterday at 1:11 it was 1:11 1-11-11(actually, I guess twice yesterday, unless you are on military time). But the grandchild whose birthday was yesterday points out that it will happen again this year--not his birthday, but the confluence. That would be November 1, aka 11-1; so 1:11 11-1-11.
We get a lot of patterned dates. Next year, we will have 12-12-12, and two years after that, 12-13-14. Last year we had 10-10-10. But do we ever otherwise get a double like this?
Update: Oh, right. My sister Sally points out that there is also 11-11-11. She recalls that 11-11 was our mother's birthday, the wrong year. And she says a bud of hers delighted himself for getting through a phone call to her that registered as received at 1/11/1. I'd say a whole bunch of people just need to get out more.
