Histories

these seventy years have twenty-five thousand, two hundred days, leaving out the intercalary month.[*](The “intercalary” month is a month periodically inserted to make the series of solar and calendar years eventually correspond. But Herodotus' reckoning here would make the average length of a year three hundred seventy-five days.) But if you make every other year longer by one month, so that the seasons agree opportunely, then there are thirty-five intercalary months during the seventy years, and from these months there are one thousand fifty days.
