DF Suggestions / Re: Add a 13th month to the dwarven calendar?

The only truly odd thing about DF timekeeping is how all the months are 28 "days" long when Fortress mode doesn't have a day/night cycle.
While the solar year isn't obligated to be the same as that of earth's, the creatures in dwarf fortress still age on an annual basis. An annual basis that mirrors our own world. As such, one would expect for days and years to both roughly mirror that of the real world's Earth. For lunar, the week system already implies that the world's in DF have roughly the same lunar cycle as our own. That's why I recommended adding another month as opposed to adding an additional 2 days to each month, since then the months would no longer be dividable by 7, which is clearly for lunar weeks.
