A ''vailee'' (<dni>vAIlE</dni>) is roughly equivalent to a month. There are 10 equal ''vaileetee'' in each hahr. Their approximate respective dates on the Gregorian calendar are: | |||

* Leefo: April 21 - May 27 | |||
* Leebro: May 28 - July 3 | |||
* Leesahn: July 3 - August 8 | |||
* Leetar: August 9 - September 14 | |||
* Leevot: September 14 - October 20 | |||
* Leevofo: October 21 - November 26 | |||
* Leevobro: November 26 - January 1 | |||
* Leevosahn: January 2 - Febuary 7 | |||
* Leevotar: Febuary 7 - March 15 | |||
* Leenovoo: March 16 - April 21 | |||
Due to fluctuations in the length of a Gregorian calendar's year versus a D'ni ''hahr'', these dates shift back and forth by as much as a couple of days in either direction from year to year. | Due to fluctuations in the length of a Gregorian calendar's year versus a D'ni ''hahr'', these dates shift back and forth by as much as a couple of days in either direction from year to year. | ||

Each yahr contains 25 pahrtahvotee; accordingly, each gahrtahvo contains five pahrtahvotee. This is also the unit of time that is referred to as "''n''th bell" in the [[Book of Ti'ana]]. The clocks found in many D'ni neighborhoods also use this division of time. Older official descriptions of the D'ni system did not mention this unit, and merely described the gahrtahvotee as being divided into 25 tahvotee. Most, if not all, explorer-written D'ni clock programs still rely on this older description. | ||

The journals that appear in [[Riven (game)|Riven]], [[Myst III: Exile|Exile]], and [[Myst IV: Revelation|Revelation]] are dated using an odd sort of shorthand that doesn't seem to match up to the actual surface dates of the events. However, this is due to the way in which D'ni dates (written in base 25) were converted to our numeric system of base 10. | The journals that appear in [[Riven (game)|Riven]], [[Myst III: Exile|Exile]], and [[Myst IV: Revelation|Revelation]] are dated using an odd sort of shorthand that doesn't seem to match up to the actual surface dates of the events.

These dates are given in year.month.day form. For example, Gehn's journal in Riven states that Catherine arrived on "86.9.29", which is Leevotar 29, 9461 (surface date March 15, 1806). The year part of the date is in a shorthand form, much as we might write "04" instead of "2004", leaving off the century part of the year. The shorthand is based on the D'ni century (''hahrtee fahrah''), which is 625 years long, or <dni>100</dni> years in base-25 notation. The current D'ni century began in 9375 DE (<dni>%00</dni> in base 25), or | These dates are given in year.month.day form.
