There available solutions are:
•Use a simple font to display 23/30 and 24/31 fractions in 3 styles that roughly corresponds to the general typographic families of serifed, sans-serif and fixed-space.
•Use XPress Tags to fully specify the manner in which each element of the 23/30 and 24/31 fractions. This option is not supported by InDesign.
•Use native formatting to specify the formatting of each individual part of 23/30 and 24/31 fractions (namely; 23, 24, 30, 31, and the separator / whose text can be overridden).
There are also some ways of dealing with the issue of displaying months requiring 6 weeks in a layout that only has 5 week rows, without the use of 23/30 and 24/31 fractions.
•The wrap to top option moves days 30 and 31 of the 6th week to the top-left of the minicalendar.
•You can also use the display 1 and 2 on top option to move days 1 and 2 above the first row.
These various options, and their advantages and disadvantages, are discussed in the corresponding topic on minicalendar options.
