Source-derived summary

The twenty-eighth of the month or twenty-eighth day of the month is the recurring calendar date position corresponding to the day numbered 28 of each month. In the Gregorian calendar (and other calendars that number days sequentially within a month), this day occurs in every month of the year, and therefore occurs twelve times per year. Because the month of February only has 28 days outside of leap years, this is the highest day number that appears on the calendar in every month of every year.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 145-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Twenty-eighth, month and twenty-eighth providing the first useful test.
Editorial analysis

Why this record matters

Critical limits
