I sometimes see the 11:11. I googled 11:11 and I found the same info.
There's a Rufus Wainwright song called 11:11... (almost everything is on the songs

).
What's recurrent for me is the number 22. That sites talks about number patterns that you may see repeated and its relations to some "guardians"...
22 is related to "ABC22", a certain guardian.
The 22 is in almost everywhere I go or everything I am. And many many times I look at the clock and it's the minute 22.
Now for skeptics... the 22 is on... my bithday date, my social welfare card, my chess license, my desk at the swimming pool, some important place I use to go, three times always repeated on the site I visit more often, .... etc
This might be just probability... imagine a card plate of four digits, the probability of having a 22= 10x10 (a digit being 2 and the next one too) divided between 3 times (because you may found it on the left, on the middle or in the right or the plate). That's like 1 out of 33.
And I see much more card plates with the 22 than 1 out of 33.
Similar calculations can be used for other probabilities.
