It is used in the standard iCalendar file format defined in RFC A big advantage of the ISO "basic format" is that a simple textual sort is equivalent to a sort by date. It is also extended through the universal big-endian format clock time: Gregorian, month-day-year MDY [ edit ] See also: This date format was commonly used alongside the little-endian form in the United Kingdom until the midth century and can be found in both defunct and modern print media such as the London Gazette and The Timesrespectively.
In the United States, it is said as Sunday, November 9, although usage of "the" isn't uncommon e. Sunday, November the 9th, and even November the 9th, Sunday, are also possible and readily understood. Sunday, November 9, Nov. The ordinal was common in the past, and is still sometimes used 4th July or July 4th. Gregorian, year-day-month YDM [ edit ] Standards[ edit ] There are several standards that specify date formats: In the United Statesdates are rarely written in purely numerical forms in formal writing, although they are very common elsewhere; when numerical forms are used, the month appears first.
In the United Kingdom, while it is regarded as acceptable albeit less common to write month-name day, year, this order is never used when written numerically.
This can be clarified by using four digits to represent years, and naming the month; for example, "Feb" instead of "02".

The ISO date order with four-digit years: Easter was the Sunday after the 15th day of this moon, whose 14th day was allowed to precede the equinox. Where the two systems produced different dates there was generally a compromise so that both churches were able to celebrate on the same day.
By the 10th century all churches except some on the eastern border of the Byzantine Empire had adopted the Alexandrian Easter, which still placed the vernal equinox on 21 March, although Bede had already noted its drift in —it had drifted even further by the 16th century. That approximation built up an error of one day every years, so by the 16th century the lunar calendar was out of phase with the real Moon by four days.
European scholars had been well aware of the calendar drift since the early medieval period. Bedewriting in the 8th century, showed that the accumulated error in his day was more than three days. Roger Bacon in c.

Dantewriting c. The first attempt to go forward with such a reform was undertaken by Pope Sixtus IVwho in invited Regiomontanus to the Vatican for this purpose.
However, the project was interrupted by the death of Regiomontanus shortly after his arrival in Rome. Numerous publications over the following decades called for a calendar reform, among them two papers sent to the Vatican by the University of Salamanca in and but the project was not taken up again until the s, and implemented only under Pope Gregory XIII r. Preparation Inthe Council of Trent authorized Pope Paul III to reform the calendar, requiring that the date of the vernal equinox be restored to that which it held at the time of the First Council of Nicaea in and that an alteration to the calendar be designed to prevent future drift.
This would allow for a more consistent and accurate scheduling of the feast of Easter. Ina Compendium was sent to expert mathematicians outside the reform commission for comments.
Some of these experts, including Giambattista Benedetti and Giuseppe Moletobelieved Easter should be computed from the true motions of the sun and moon, rather than using a tabular method, but these recommendations were not adopted.
He also produced an original and practical scheme for adjusting the epacts of the moon when calculating the annual date of Easter, solving a long-standing obstacle to calendar reform. Ancient tables provided the sun's mean longitude. Tycho Brahe also noticed discrepancies. He noted that it is consistent with the tropical year of the Alfonsine tables and with the mean tropical year of Copernicus De revolutionibus and Erasmus Reinhold Prutenic tables. The three mean tropical years in Babylonian sexagesimals as the excess over days the way they would have been extracted from the tables of mean longitude were 14,33,9,57 Alfonsine14,33,11,12 Copernicus and 14,33,9,24 Reinhold.

All values are the same to two places Thus Pitatus' solution would have commended itself to the astronomers. Firstly, he proposed a correction to the length of the year.
The mean tropical year is The discrepancy results in a drift of about three days every years.
Lilius's proposal resulted in an average year of At the time of Gregory's reform there had already been a drift of 10 days since the Council of Nicaea, resulting in the vernal equinox falling on 10 or 11 March instead of the ecclesiastically fixed date of 21 March, and if unreformed it would drift further.
Lilius proposed that the day drift should be corrected by deleting the Julian leap day on each of its ten occurrences over a period of forty years, thereby providing for a gradual return of the equinox to 21 March.
Lilius's work was expanded upon by Christopher Clavius in a closely argued, page volume. He would later defend his and Lilius's work against detractors. Clavius's opinion was that the correction should take place in one move, and it was this advice which prevailed with Gregory. The second component consisted of an approximation which would provide an accurate yet simple, rule-based calendar.
Lilius's formula was a day correction to revert the drift since the Council of Nicaea, and the imposition of a leap day in only 97 years in rather than in 1 year in 4. The proposed rule was that years divisible by would be leap years only if they were divisible by as well. The year cycle used for the lunar calendar was also to be corrected by one day every or years 8 times in years along with corrections for the years that are no longer leap years i.
