Back in the olden times B.I. (before internet) I was a high school student in Winnipeg, during the 80s,and every year we had the above noted. Why has been lost to the mists of time, but I do have a button from that time and we did wear the apparel. Anyone else ever hear of this and what did it mean? I know it was bigger than my high school, but my Google fu has failed me. ---

Googling, I can find a few LGBT events, but they seem to be pretty recent in origin, and its hard to picture a HS in the 80’s being progressive enough for such an event. But I also found two cryptic links for an “International Yellow T-Shirt day” for the last Thursday in April (so, um tomorrow) that has been going on for 36 years. [Here’s](https://www.facebook.com/events/554731651333965/) the Facebook page. I imagine that’s what the OP is referring to, but it just seems like somebodies in-joke with his friends. Not sure how he got Canadian HS to participate 30 years ago. My WAG, it started as kind of a hippy joke that briefly caught on in the 80’s, and a few people are keeping it going 30ish years later. ---

Here’s an even more cryptic [web page](http://allthingsyellow.blogspot.com/). The author is from Winnepeg, so presumably its the same thing. But Its a blog called “All Things Yellow”, which contains a single entry, a blogpost that contains nothing but the phrase “IYTSD is drawing nigh.” I feel like I’m finding clues to some ancient Da Vinci code type secret cult. If I end up dying in mysterious circumstances in the next few weeks, it means I got too close. ---

The single entry blog I linked to dates from 2005. Which means someone has paid fees to keep the domain name for ten years ---

The Facebook entry is perfect! Thank You! You are right in that it had nothing to do with endometriosis or LGBT events. Time to grab my yellow t-shirt! As to why it started at all I have to look a little further. ---
