The Zanaryan calendar (ZT) has only nine months, each of which derive from their numeric position in the calendar combined with the Zanaryan word for "month", sharh.

The Zanaryan calendar began in 1,060 XA and is 7,040 years older than the Gregorian calendar (AD/BC). AD + 7040 = ZT
BC - 7040 = ZT
XA + 1060 = ZT
ZT - 1060 = XA

The official Zanaryan calendar (ZT) was devised by astrologers in the Temple of Farahij?. Seasons are listed for the southern hemisphere.
