maskday 

The day you set aside for the week, to wash all of your fabric masks, forcing you to use those cheap light-blue paper masks that always end up with one broken string, and hang funny on your face.

Yeah, its Maskday, and yes, my light-blue paper mask has a broken string, and hangs on my face kinda funny.

Masday 

The eigth day of the week which lies between sunday and monday,
Correctedly determined as the masday feeling instead of the monday feeling.
The extra day confuses the annual calendar which is why there is not 4 solid weeks to a month.
And also the reason as to why there is a leap year every four years.

Hattie:"jp how was masday"
Whitey:"lmfao!"
Jp:"T'was okay thanks"

National Mask Day 

A future annual event when companies and schools allow employees and students to wear their own DIY face masks in remembering what they used to wear in a pandemic to protect themselves and others.

WHO couldn’t get the unanimous approval of member countries to commemorate National Mask Day post-pandemic.
