You need to be on Discord to find them all, and the discussions in the #events channel can also help.

Some general tips:

Some of them are in obvious places.
Some are in rarely-visited corners of the site.
Some can be found by clicking around.
Some can be found by searching.
You will know when you found one, there's not any ambiguity.
