Conversion Charts


A Pernese Turn consists of 13 months and one Turn's End Day, which equals out to one Terran (Earth) year--easy to convert with this handy conversion chart. (NOTE: This doesn't work for Leap Year, when February 29th is the day that went between.)

This page contains two charts: one for converting the years to turns and another to convert the Terran month and day to the Pernese month and day.

How to use this chart:
Simply find the year you're looking for and follow that line to the Pernese turn. The month and day are just as easy: find the month/day you're looking for and follow that line to the numerical month and day combination for the Pernese date.

Pern dates are listed YY.MM.DD (YEAR.MONTH.DAY), so for instance, May 6, 1993 would convert to a Pernese date of 7I.195.05.14; the 195th turn of the Interval, 5th month and 14th day. So, to come up with a complete Pernese date, find the proper Turn and add the proper month/day.
