There are two systems of naming months in use: one based on the zodiac, and one based on numbers. The place structure is "x1 is foomonth in year x2 in calendar x3"; this is not according to jvojva but makes it easy to specify dates as "the day nth of the foomonth of the year mmmm".
There are also systems of naming the days of the week based on Oriental elements and numbers.
|Oriental el. name
|zeldei or nondei
Note that Sunday in Lojban is either day seven or day zero, depending on your perspective.
