First, I am not so sure the Klingons would even have star dates. Going on pure guess work here, I would suspect that federation star dates exist due to the need to administer what passes for an empire. What purpose they actually serve is known only to Roddenberry and if we could ask him, I am sure that he would have at least as many explanations as he did for the Klingon forehead.
“like star dates” Of course but does it have to be fully compatible with the federation system? If I am going to take the “purist” tack here, I would tend to believe that whatever the system is in the Empire, it was fully in place before contact with the federation had been established. If you read my previous post further, I did advance a perfectly good system that meets that criteria. It just was not a star date in the sense that the federation uses.
Stardates predate the Federation. In fact, Earth had to adapt to them to fit in. Klingons having stardates doesn't seem so farfetched.
From what I have gathered Qo'noS's star orbits a red giant that went supernova billions of years ago, destroying the planets that were in it's previous biosphere. Qo'noS had the good fortune to be in the new biosphere. An older larger star like that will need to keep it's planets further away, giving them much longer years than younger stars, like our own.
Where did you find this information?
My original concept was for a system that was reasonably easy to convert, but not a strict replacement system. My original post was simply looking for any canon names for days or months that anyone had come across, the debate on the calendar system took off from there. Remember there was even one post that said Klingons wouldn't have months or weeks, so there is an awful lot of room for interpretation here. I have never been that far from my original concept of something that was intended for fans to use on a larger scale than simply a writers bible.
So, we have "Maktag," a month with at least 43 days. There's also "nay'Poq," the month in which the Klingon savior was fortold to be born.
