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".
|English name||Zodiac name||Number name|
There are also systems of naming the days of the week based on Oriental elements and numbers.
|English name||Oriental el. name||Number name|
|Sunday||soldei||zeldei or nondei|
Note that Sunday in Lojban is either day seven or day zero, depending on your perspective.
