Each month has either 28, 30, or 31 days during a common year , which has
365 days. During leap years , which occur nearly every 4 years, we add an
extra (intercalary) day, Leap Day , on 29 February, making leap years 366
days long. | |
lubridate/months2_10_0.txt | ## From 10 to 12 Months
Our current Gregorian calendar and its predecessor, the Julian calendar ,
both have 12 months. However, the month names we use today are derived from
the Roman calendar , which initially had only 10 months, with the calendar
year starting in March ( Martius ). | |
lubridate/en-gb9_31_0.txt | ## The date format in American English
When you prefer to write the date in American English, usually the month comes
before the day, followed by the year. If we use the same example as before:
The 6th day of the month September, in the year 2019, then the date in
American English should be written as: | |

The last two date formats are more formal. The “the” and “of” are optional but
if you do use them, you must add both “the” and “of.” It is incorrect to say
only “6th of September” or “the 6th September.” | |
lubridate/en-gb9_26_0.txt | As for the year, commas are not necessary when you write the date in British
English, but you can if you prefer this style.
If you wish to add the name of the day, it should come before the date, and
should either be separated by a comma or joined by “the” and “of.” | |
lubridate/en-gb9_22_0.txt | In British English, which is the type of English mainly used in Australia, the
day is followed by the month, which is then followed by the year. The 6th day
