Radrolf Calendar
Summary
The Radrolfen calendar is similar to the Jimmian calendar and Earth calendar in that the stellar year is broken up into months and each month broken into days. The number of days each month is typically 49 (as with the Jimmian calendar but the number of months is ten (10) rather than (9) and the variable month is in Spring, rather than Summer.
Jimmian and Radrolf have no distinct Moons orbiting them but they do have a scattering of asteroids circling, each with a larger mass coalescing around larger pieces representing a substantial-enough mass to drive a slight tidal force.
There are typically 459 days in the Radrolfen year, with an extra day every seventeen years. This still leaves a minor drift that has been adjusted for countless times over the centuries.
Days are further divided into twenty-eight (28) hours of 49 minutes each and each minute is further divided into 49 seconds.
Like Jimmians, Radrolfens base their numerical system on the cardinal number seven (7), thus they count 100 seconds per minute and 100 minutes per hour and 40 hours per day. They also count 100 days per month.

Months
Radrolf's year is divided into ten (10) months. Each new year begins in Midsummer with the Month named Tzuñol. The Jimmian months are:
| Tzuñol | 49 days |
| Khrañol | 49 days |
| Alvtyne | 49 days |
| Viljtyne | 49 days |
| Baghtyne | 49 days |
| Theotyne | 49 days |
| Thuzñol | 49 days |
| Khryjhet | 49 days |
| Viljhet | 49 days |
| Fylñol | 18/19 days |
Each month has 49 (decimal) days (100 septimal), except Fylñol which has 19 (decimal) days (25 septimal) every 17th year and 18 (decimal) days (24 septimal) otherwise.
