A worldwide fan celebration day happening on April 13th, also known as 413 or HSDay. Is the conmemoration of the day on which Adrew Hussie, creator of Homestuck , posted the first page of the webcomic on MSPaintAdventures in 2009. The day is known by Homestuck fans as the day on which, if you are a homestucker (strong follower of the comic), you have to cosplay and talk about Homestuck as much as possible. This means going outdoors, or to fan conventions, reunions which usually concludes with a massive internet traffic consumption, mostly on tumblr.

It has to be added that some fans might celebrate HSDay on a random day for no reason.
Example 1
Hey, tomorrow is March 14th, it's Homestuck Day.

Great, I'm going to start working on my Karkat cosplay.

Example 2

Sep 14 Word of the Day
Micro marriging is when your partner manages your personal day-to-day tasks with you much like a Micro Manager at work.
Wife: “Have you put the sheets out to dry and put the towels on?”
Husband: “Yes. You know I am a grown adult also used to live alone so you do not need to micro marrige me”
