The Dundulanyä calendar counts the 418-day Eventoan solar year (''naṃśāla''), divided into 14 months (''asānai'', sg. ''asāna'') of varying length (30 days on average), as well as a concurrent (not numbered) shorter cycle, called ''juñśätanä'' (from Lannä ''zunosä tanäy'' "count of days") of 216 days, which forms the basis of the "week" system, dividing that number of days into 18 "weeks" of 12 days each.

The solar year is not exactly 418 days long (the exact amount being roughly 418.1668 days), so that each sixth calendar year is a 419-day long leap year, adding one day at the end of the last month. The 418- or 419-day year and 216-day ''juñśätanä'' are grouped together into 78-year cycles (151 ''juñśätanä''), where the 78th year is a leap year (the thirteenth in such a cycle) and the 151st ''juñśätanä'' also adds a single day (hence having a length of 217 days), so that both counts end on the same day (the 32.617th of the cycle) at the end of the 78th solar year / 151st ''juñśätanä''.

The start of the calendar year is on the Southern hemisphere fall equinox, while days start at dawn. Months are grouped according to astronomical seasons of the Southern hemisphere, but it is the same nevertheless in the few areas of the Dundulanyä world north of the Equator; these are not immediately related to climatical seasons, as the Dundulanyä heartlands of Mandabuda have a monsonic climate with two distinct seasons and most of the Dundulanyä live in areas with tropical or equatorial climates.
