Excerpt from A Perpetual Calendar for Old and New StyleBy the Julian Calendar the year consisted of 365 days and 6 hours, instead of the true time. Of the duration of a solar year, thus making the year too long by about 11 minutes. From the time of the Council of Nice to the time of Gregory, this differ ence had amounted to ten days. In order to obviate this error, it was ordained that the year 1582 should consist of 365 days only, and that ten days, between the 4th and 15th of October, should be thrown out of the Calendar of that year, and also, to prevent further irregularity, that no year terminating a cen tury should be bissextile, excepting each fourth of such years. Three days are thus retrenched in every four-hundred years, because the lapse of eleven minutes for every year makes very nearly three days in that period, leaving an error of one day only in about 5200 years.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
