How to appropriately display the day of the month by itself? Is 日‪ required, optional, or undesirable?


I know that an acceptable way to display (this is in a computer program) a
full year/month/day date is like so:

> 2013年5月19日‪

What If I wanted to display the day **only**? Does the following look right,
OK, or weird to native Japanese user? Is the 日‪ character required, optional,
or undesirable in this case?

> 19日‪

In other words, would it look better if it was just the number?

> 19




You would be better off using the 日. The same in other language, without unit
the number does not mean anything.
