Is April 24, 2021, "National Rape Day"?" No, that's not true: there is no evidence this event is expected to happen, and there is some evidence that it may have originated as some internet trolls' idea of a joke.
Although the claim has primarily spread on TikTok, it also appeared on other social media platforms. A Facebook post (archived here) published on April 17, 2021, warns about the day of assault. The caption says "Stay Safeee Yall .!!!" and includes a screenshot of another Facebook post that stated the following:

This is what the post looked like on Facebook at the time of writing:

All of the designated dates for the day were in April. Many users created definitions that push back on the 2021 version of the day:

An archived 4chan thread from April 18, 2021, discusses how trolls can take advantage of the sensationalism of the supposed day by weaving in bigoted tropes that would upset various marginalized groups. One of the points of advice was for trolls to say that the creators of the day were all Black and/or refugees.
