Do people outside of the USA use two-part date abbreviations for the current year? For instance, representing the last day of May, you might see someone enter 5/31 into a date field.Do international users do something similar? In a country that ordinarily uses dd/MM/yyyy would they use 31/5 or some such?

Yes, there are different ways of entering a data in a short format. The CLDR chart on Md notations illustrates the variation. Many languages use d/M notation, but d.M, M-d, and other notations are used, too. The notations used in CLDR are explained in the LDML specification; Md stands for month and date notation consisting of shortest possible numeric notation for month, M, and day, d, with language-dependent punctuation and order.The M/d vs. d/M case is particularly problematic, because both notations are used in English, as well as in other languages.Data consisting of two numbers separated by a slash should be accepted on input only if you can be sure to know which of the two different notations M/d and d/M is meant. When can you be sure of such things? Just giving people instructions doesnt guarantee anything. Calendar widgets for input have their problems, but at least they avoid the confusion between 4/7 and 7/4.
