I work banker's hours at the office.

The project required thousands of man-hours to complete.

I have been working for H-hours straight.

I love going to happy hours with my friends after work.

The talent show was full of amateur hours.

I have scheduled several block hours for studying this week.

I will meet you after hours.

We had an after-hours party at the office.

The temporal hours fly by when you're having fun.
