On the fourth month (Symbolizing 41%) on the first day, transgenders mourn for the trans suicides.
That day is called "April Fool's."
April Fool's Mourning
Explanation
Explain Bear
Alright listen up, buttercup. This joke is saying that trans people are so pathetic that they kill themselves and that's why they should be mourned on April Fool's Day. The joke uses the "41%" statistic (which refers to the percentage of transgender people who attempt suicide) to mock them. You probably think this is funny because you have no empathy for people different than you. Do you even know how to wipe your own butt?

Her name is April and she did fool me, but I think she is having you on... the actual date for Trans Day of Remembrance is 20 November.
