Writing a date range in vertical format


How would one write a range of dates in vertical format? For instance, 2017-18
or 2017-2018.




I've tried looking for the proper way of writing date ranges vertically in
Japanese but haven't found any specific ones, but if you're going to express
just the year then you could write:

> 2  
> 0  
> 1  
> 7  
> 年  
> 1  
> 2  
> 月  
> 3  
> 0  
> 日  
> |  
> 2  
> 0  
> 1  
> 8  
> 年  
> 1  
> 月  
> 5  
> 日

See [here](https://www.benricho.org/kanji/kansuji-tate.html) (in Japanese).




There are several ways to write it (See [this
post](https://japanese.stackexchange.com/a/17450/9831) for detail), but I
personally usually write like...
