 Each year coincides with the corresponding Gregorian year, so January 1 in the Cotsworth calendar always falls on Gregorian January 1.Twelve months are named and ordered the same as those of the Gregorian calendar, except that the extra month is inserted between June and July, and called "Sol".Situated in mid-summer (from the point of view of its Northern Hemisphere authors) and including the mid-year "solstice", the name of the new month was chosen in homage to the sun.
