Lojban/Dates

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
January	kanbyma'i	pavma'i
