Our project is scheduled to be completed on the sixteenth day of the month.

We have our wedding on the thirtieth.

There is a friend's wedding on the thirtieth of this month.

The thirteenth day is my birthday.

I want to learn about the history of Jūnishi.

He made a model of a dodecahedron.

He said, 'Each person has one life, like a pike or a shrimp,' and decided to live his life with care.

This shape is a parallelogram.

He is working round the clock.

My four treasures of the study are a fountain pen, a pencil, an eraser, and a ruler.
