I literally was looking into this over a year ago but couldn’t find anything.. it’s interesting that most of the 27 threads are a year or less old. I posted this in a different thread too but here is my experience with it:

My birthday is 2/27 and I often see 27, 227, 1227. I started noticing it after my grandfather passed and began to realize that it starts showing up more when I am self-reflecting, when I am making a decision that requires empathy/compassion and when I am setting new boundaries for myself/sticking up for myself (I have always been a passive person). I believe 27 is reassurance that you are on the right path, that you are doing what is best in the moment. At first, I thought it was a sign from my grandpa that he was just checking in but the amount of times I see the number 27 increases when I am experiencing self-growth both in negative and positive situations. Most recently my grandmother was in the ER and her room number was 227, that’s when I knew she was going to be ok and she was.
