Notes

The calculation uses the Martian sol duration (24 h 39 m 35.244 s) and a calibration reference compatible with the telescopic epoch of the Darian/Utopian calendar.

The calendar divides the year into 24 months. Months 6, 12, 18, and 24 have 27 sols; month 24 has 28 sols during leap years.

References consulted for this implementation: the general description of the Darian calendar, its telescopic epoch, and the structure of months and leap years in OPS-Alaska and Mars Calendar, as well as Grokipedia's encyclopedic summary of the Darian calendar. class=""
