Steve, what are you talking about ???? And what do those numbers have to do with anything at all ??? Confirmations of what ?????  And they all came up on what sign ???
Here is your post, and it is most confusing to me.
 

On the way home today, I saw that the time was 3:21
The temperature was 44,

A telephone number ending in 777 all on the same sign at the same time.

I almost crashed my car!
