There are a number of applicatios in the cavern, for which we need to know how D’ni time works. The DRC released a document a number of months ago explaining how it all worked, and placed copies of it in some of the Neighborhood classrooms.
Much as with anything else in D’ni, the timing system can appear to be complicated at first; but that is mostly because, as with measurement and math, D’ni based their time on their favorite number 5.
The terms in D’ni time are as follows:
- hahr – roughly a year
- vai-lee – a D’ni month. (hahr divided by 10)
- yahr – a D’ni day. (There are 29 yahr in a single vai-lee)
- gahr-tah-vo – A day segment. There really isn’t a good Earth equivalent. (5 gahr-tah-vo-tee in a single yahr.)
- pahr-tah-vo – This would be similar to an Earth hour, save that it has an extra 13 or so minutes in it. (gahr-tah-vo-tee have 5 pahr-tah-vo in them.)
- tah-vo – Again, the closest similarity between this denomination of time and those on earth would be the quarter-hour. There are 5 tah-vo-tee in a single pahr-tah-vo
- gor-ahn – 25 gor-ahn-tee in a single tah-vo
- pro-rahn – the closest similarity to an Earth second. Is about 1.5 seconds. There are 25 pro-rahn-tee in a single gor-ahn.
If I’ve confused anyone here with my attempt to simplify the DRC’s time document, I apologize. I will note that, the difference between ‘gor-ahn’ and ‘gor-ahn-tee’ is that one is singular, and the other plural. (That really messed me up for a little while when trying to read the original document.)
And in all, if you’re trying to figure out D’ni time, break our time down to seconds, and work your way up from pro-rahn-tee. Here’s an example:
14 surface days = 14 x 24 x 60 x 60 = 1209600 surface seconds.
1209600 / 1.4 = 864000 pro-rahn-tee
864000 / 25 = 34560 gor-ahn-tee
34560 / 25 = 1382.4 tah-vo-tee
1382.4 / 5 = 276.48 pahr-tah-vo-tee
276.48 / 5 = 55.296 gahr-tah-vo-tee
55.296 / 5 = 11.0592 yahr-tee
You could continue this to figure out fractions of a month and year, but the result we have here is this:
14 surface days = approx. 11 yahr-tee (or D’ni days).
The method of calculation I’ve posted above is possibly the most accurate method of figuring out the conversion, however, the document released by the DRC contains some approximations that would make converting from surface time to D’ni time a little faster, if less accurate.
eg) 14 surface days / 1.26 = 11.11111 yahr-tee
