A niner is typically referred to by blue collar working folk. It describes the amount of hours worked in a day. If you work a normal 9 to 5 job, you take the first hour you start working, and use it as reference for the total hours worked in a day.

For example- a 9am-5pm work day is 8 hours total, but since you started at 9am, you can call it a NINER.

A niner is commonly associated with high stress levels...
"man, that NINER really did me in today..."
"I'm so exhausted from my week of NINERS"

"some days I feel like I worked a NINER, even though it was just a fiver"
