As an expert in the field of history and timekeeping, I've spent a considerable amount of time studying the evolution of calendars and the fascinating ways that different cultures have sought to measure and organize time. The question you've asked is quite intriguing as it touches upon a historical aspect of calendar reform and the lengths to which societies have gone to ensure that their calendar year aligns with the solar year and the changing of the seasons.
In the modern Gregorian calendar, which is the most widely used civil calendar today, no month has 27 days. The lengths of the months are as follows: January (31 days), February (28 days, 29 in a leap year), March (31 days), April (30 days), May (31 days), June (30 days), July (31 days), August (31 days), September (30 days), October (31 days), November (30 days), and December (31 days).
However, the reference you've provided points to an interesting period in the history of the Roman calendar. The Roman calendar, as originally conceived, was a lunar calendar with ten months and a total of 304 days. It was quite different from the calendar we use today and required frequent adjustments to keep it in sync with the solar year.
During the time of the Roman Republic, the calendar was occasionally realigned with the solar year by the insertion of an intercalary month. This additional month was called "Mercedonius" or "Intercalaris" and was inserted after February. It was intended to correct the discrepancy between the lunar year (about 354 days) and the solar year (about 365.24 days). The length of this intercalary month could vary, and at certain intervals, it was set to 27 days.
The decision to insert an intercalary month was made by the Roman priests, specifically the Pontifex Maximus, who was considered the chief authority on religious matters and also had the responsibility of overseeing the calendar. The insertion of the intercalary month was a complex process and was not done annually but rather at irregular intervals, depending on the judgment of the Pontifex Maximus.
It's important to note that the practice of inserting a 27-day intercalary month was not consistent and was eventually seen as problematic due to its irregularity and the potential for political manipulation. This led to the eventual reform of the calendar by Julius Caesar, which introduced the Julian calendar. The Julian calendar was a solar calendar with a fixed number of days in each month and a leap year system to account for the extra quarter day in the solar year.
The Julian calendar was later refined by Pope Gregory XIII, resulting in the Gregorian calendar that we use today. The Gregorian calendar has a more accurate leap year system and is a solar calendar, which means it is designed to align with the solar year, not the lunar cycle.
In conclusion, while no month in the current Gregorian calendar has 27 days, the historical context provided by the Roman calendar does offer an explanation for how a month could have had 27 days at certain times in the past. This practice was part of an effort to maintain the alignment of the calendar with the solar year, a challenge that has been faced by many societies throughout history.

February was shortened to either 23 or 24 days at certain intervals in the Roman calendar, in which a 27 day intercalary month was inserted after February to realign the year with the seasons.
