Character creation date of birth shorthand notation incorrect

[Enkidoh]

Players have noted this repeatedly since the Beta test in 2013 and SE have actually stated it's working as intended - it's just an oddity of the Eorzean calendar (an Eorzean month or 'moon' is 32 days for every month, with a year of 384 days, and so some Earth dates have to be doubled up to fit - they tried to make a 1-1 equivelant in the Gregorian calendar as much as possible but ultimately the discrepency between the two calendars is just too great).

Unfortunately, as this is working as intended it's not something they're going to change (as bizzare as it is).
