Occasionally you do not know a complete date, such as:

13 (Date only known)
13 APR (Date and month only known)
APR (Month only known).

What/how do people code this in their software?

Do they:

Key it in the date field?

Include it as a note?

Some other option.

It depends on the program and what it lets you do. If programs allow date phrases, which are dates in any format whatsoever, then that would be fine. A date phrase in GEDCOM is any expression enclosed in parenthesis, e.g.:

2 DATE (April 13)

If that is not allowed in your program, I'd just add it as a note, e.g. NOTE Aunt Helen's birthday was on April 13, but we never knew how old she was.

GEDCOM requires a year, or a year an a month, or a year and a month and a day for the date to be expressed in the valid date format of: dd MMM yyyy - which prevents ambiguity and allows sorting of dates for programs that want to do that.
