How long were the parents gone for?

i don';t think it's ever clearly stated, is it?

"He must've thought it was white boy day. It ain't white boy day, is it?"

I do believe the scene with Miles' birthday and the scene where Buck shows Bug the hatchet had to take place during the weekend, I also thought the bowling scene had to take place on a Friday night.

Here is the timeline when I felt the events took place.

The beginning scene along with the dinner scene was likely on a Tuesday or a Wednesday

The scene where Buck and Chanice were having dinner together was likely on a Wednesday night

The scene where Cindy's father had a heart attack likely happened in the wee hours of Thursday morning

The scene where Buck first starts doing laundry was likely on a Friday

The scene where they went bowling was likely on a Friday night

The scene with Miles' birthday was likely on a Saturday

The scene where they go pick up Tia was most likely on a Saturday or Sunday night

The scene where Buck confronts the vice principal was likely either on a Tuesday or a Wednesday

The scene where Buck calls Chanice telling him that he misses her was definitely on a Wednesday night

The scene where Chanice confronts Buck about him dancing with Marcie was definitely on a Thursday

The scene where Buck tries to take the kids to a racetrack along with him finding Tia was definitely on a Friday night

The scene where the parents arrive home was likely on a Saturday.
