The Exact Date Of Ice Cubes Good Day

A chap named Donovan got his Inspector Gadget on and pin pointed the date that Ice Cube had his 'Good Day'. The evidence is below.

"Went to short dogs house, they was watching Yo MTV Raps"

Dates between Yo MTV Raps air date (AUGUST 6 1988) and the release of the single (FEBRUARY 23 1993) where the Lakers beat the Super Sonics:
Nov 11 1988    114-103 
Nov 30 1988    110-106

CLUE 5: 

"Got a beep from Kim, and she can fuck all night" 

Beepers weren’t adopted by mobile phone companies until the 1990s. Dates left where mobile beepers were availible to public: 

Jan 18 1991 
Jan 20 1992 

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...far too busy to be lounging around the streets playing bones yellin domino.

Therefore, the ONLY day where: 
- Yo MTV Raps was on 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…
