January 20, 1992: It was a Good Day

Skateboarder Donovan Starin was the first to publicize the Good Day, as described in Ice Cube’s hit “It Was A Good Day.” As Donovan researched, the facts point to a single possible day, in 1992. “The ONLY day where: Yo! MTV Raps was on the air, it was a clear and smogless day in Los Angeles, beepers or pagers were commercially sold, Lakers beat the SuperSonics and Ice Cube had no filming commitments was January 20, 1992,” Starin pointed out.

Outside of not having bacon that morning, for Mr. Cube, it was indeed a good day.

The basic clues are in the lyrics to the song, according to @DonovanStrain:

CLUE 6:
Ice Cube starred in the film “Boyz in the Hood” that released late Summer of 1991 but was being filmed mid-late 1990 early 1991 and Ice Cube was busy on set filming the movie Jan 18 1991 too busy to be lounging around the streets with no plans. Ladies and Gentlemen..

The ONLY day where:
Yo MTV Raps was on the air
It was a clear and smogless day
Beepers were commercially sold
Lakers beat the SuperSonics
and Ice Cube had no events to attend was…

JANUARY 20 1992
National Good Day Day

“Just wakin up in the mornin gotta thank God
I don’t know but today seems kinda odd
No barkin from the dog, no smog
And momma cooked a breakfast with no hog (damn)
I got my grub on, but didn’t pig out
Finally got a call from a girl I wanna dig out
(Whassup?) Hooked it up for later as I hit the do’
Thinkin will I live, another twenty-fo’
I gotta go cause I got me a drop top
And if I hit the switch, I can make the ass drop
Had to stop, at a red light, lookin in my mirror and not”
