[3][4] In Brazil, dates follow the "day month year" order, using a slash as the separator.
Leading zeros may be omitted, specifically on the month, but never on the year field: 9/5/08.
For example, the above date might be very shortly spelled as "um do cinco de vinte e sete" (one of the five of twenty-seven).
Or informally as: dois do doze de mil, novecentos e sessenta e sete (two of the twelve of one thousand, nine hundred and sixty-seven).
Within a month, days are referred to as "no dia"+"ordinal number that corresponds to the date".
Let us suppose a test is set up for April 15 and hearers know what the month in question is.
