Calendar
Kerbin years are most often organized in a calender consisting of 14 months, each consisting of 31 days. The most common calender on Kerbin is the Reformed-Kulge calender which originated from Tekkia.
History
For most of kerbal history primitive calenders were used to determine seasons and predict crop yields and weather patterns. A multitude of systems were used across Kerbin varying from city to city, some based on a Solar year and others on a Munar year. In the year 1427 the king of Tekkia ordered a new solar calender be devised to be used universally. This calender was known as the Ra'an calender and consisted of 14 months and contained protocals to counter the extra 27 minutes of the year.
Reforms
In 1711 the Ra'an calender was further revised into the Kulge calender as it was found the year had 32 minutes extra, not 27. In 1802 a version of the Kulge calender with simplified names and characters was created so it could be more easily typed. This reform was not introduced until 1827 when the industrial revolution was spreading worldwide. The change was controversial as most other countries had different spellings and therefor the change would not effect them.
Subdivisions
As technology progressed, the need to predict weather more accurately grew and subdivisions were neccasary. Majority of calenders that use subdivisions had around 30 days per Month. Work schedules were organized into weeks, which tended to vary from 5-10 days. Because days are not perfectly in synch with the Kerbin year, an extra 32 minutes remains unnacounted for. This can be countered by lengthening or shortening a day, or by removing or adding days from a month.

Alternative types
An popular alternative to the Munar or Solar calenders are origin calenders, which set the baseline at the founding of the nation or the inaguration of a ruler. Sahrland for example uses two year systems, one being the Reformed Kulge calender and the other being the age of the current reigning king.
