Dominion Reckoning

The Thunderhead Dominion uses a calendar adapted from that of their near-neighbours in the Elysian Federation. It has twelve months of 30 days each, with the first day of each month being an unnumbered 'calend,' and seven additional intercalary days. Every fifth year an additional intercalary is added to maintain alignment with the solar year.
It does not use a round count, simply numbering the 'Years of Thunder' since the accession of the Thunderhead.
