The Pope tends to be a powerful guy. He can start global conversations, rock all kinds of colors, and sometimes perform miracles.
But only once in history has a pope made time literally disappear.
In 1582, thanks to then-Pope Gregory XIII, October 6thalong with the 5th, 7th, 8th, 9th, 10th, 11th, 12th, 13th, and 14thsimply didn't exist. Ten days, gone.
Why? Because of that perpetual thorn in Christianity's side: the Sun. In the 16th century, much of Europe was on the Julian calendar, the result of an earlier temporal restructuring, in 46 B.C., when Julius Caesar gathered up Rome's best mathematicians and astronomers and decided to turn what had been a 355-day lunar year into a 365 1/4-day solar one. The republic gritted its teeth through one 445-day year (known as "annus confusionis," Latin for "year of confusion"), and after that everything went mostly smoothly, with a leap day added every 4 years to account for the 6-hour surplus. No one touched the Julian calendar for nearly 17 centuriesexcept Caesar Augustus, who, legend has it, stole one day from February and added it to August, so that his month would be as long as his great-uncle's.
But there was one small problem. The Earth doesn't take 365.25 days to go from equinox to equinoxit actually takes 365.24219 days. With each cycle of the Julian calendar, human time fell behind celestial time an additional 11 minutes and 14 seconds. As the years piled up, the difference increased, and after 1600 years of deploying the same, slightly flawed algorithm, this small margin of error had multiplied into about 10 days of lag time.
Everyone realized what was going on from the beginning, but for the first dozen or so centuries of the calendar's deployment, it was an end-of-the-list kind of problem. As the mismatch got worse, though, it became more urgent, particularly to Christian religious leaders.
Way back in 325 AD, the church had held a big meetup, The First Council of Nicea, to standardize the dates of major holidays, particularly Easter. "What could be more beautiful and more desirable than to see this festival, through which we receive the hope of immortality, celebrated by all with one accord, and in the same manner?" wrote Emperor Constantine, the Council's convener. (It was particularly important to him not to celebrate it on any Jewish feast days.) They decided on the first full moon after the vernal equinox, which, in 325 A.D., fell on March 21st.
They set Easter as the first Sunday after March 21st, clocked the other saint's days and holidays off of that, and called it a year. A millennium later, the whole calendar was out of whack with the equinoxes, and therefore the seasonsas one modern historian put it, Easter "was slowly working its way toward becoming a summer holiday, and Christmas was sneaking into spring.
By the end of the 15th century, church leaders agreed that celebrating Easter on the wrong day was "a scandal." By this time, the discrepancy was also affecting sailors, merchants, farmers, and others who wanted to keep their datebooks in sync with the lunar cycles and the climate. The best hope for fixing things came from the church, who (at least compared to the fragmented governments of Europe) was more likely to act impartially. Pope Sixtus IV was the first to try, in the early 1470s, but the effort screeched to a halt when his chosen astronomer died (depending on who you ask, he was either assassinated or died in a plague).
A hundred years later, Pope Gregory XIII rolled up his sleeves and went for it in earnest. After a call for suggestions, he he was brought a gigantic manuscript. This was the life's work of physician Luigi Lilio, who argued for a slow, 10-day correction to bring things back into alignment, and a new leap year system to keep them that way. This would have meant that years divisible by 100 but not by 400 (e.g. 1800, 1900, and 2100) didn't get the extra day, thereby shrinking the difference between the solar calendar and the Earthly calendar down to a mere .00031 days, or 26 seconds.
The new lead astronomer on the project, Jesuit prodigy Christopher Clavius, considered this and other proposals for five years. He ended up agreeing with most of Lilio's ideas, but thought the extra ten days should be made up in one fell swoop. So in February of 1582, Pope Gregory issued "Inter Gravissimus," a papal bull explaining how he was changing time. And half a year later, people in the more religiously obedient sections of Europe went to sleep on Thursday, October 4th, 1582, and woke up on October 15th. (It was still Friday, though. Nobody wanted to skip Friday.)
The disappeared days caused a certain amount of turmoil. Some people worried that Heaven had missed the memo, and that prayers timed to particular saints' days wouldn't go through. Rents and wages needed to be recalculated, and birthdays and anniversaries moved ten days later in order to be accurate. There were riots. Plenty of countries couldn't or wouldn't make the switch for months, years, or even centuries. By the time British Parliament came around, citing "divers inconveniences" too bad to ignore, it was 1752 and they (and their colonies) had to skip 11 days. They had riots too, and to this day, people aren't quite sure where in February to pin George Washington's birthdaythe 11th or the 22nd.
As the changes cascaded through Europe, crossing borders from Julian to Gregorian countries was basically time-traveling. The last country to switch from Julian to Gregorian was Greece, which finally skipped its 12 days in March of 1924.
Since then, things have been pretty steady. But the march of time is inexorable, human systems remain flawed, and by the year 4909, we will have outstripped the solar year by an entire day yet again. Here's hoping future popes, tyrants, or alien overlords have the presence of mind to make the necessary adjustments, and to never, ever skip a Friday.
Secular view, ping!
A good history lesson.
I remember about the change in the calendar story, imperfectly, from childhood when my 4th grade teacher told about Great Britain making the change after George Washington was born, thus he had “two” birthdays and we celebrate the 2nd Gregorian Calendar one on Feb 22.
great article - thanks for posting
This fellow says the standard should be the Vernal Equinox Year rather than the Solar Year:
http://www.hermetic.ch/cal_stud/cassidy/howlong.htm
The Gregorian Calendar gains a day on the Vernal Equinox every 6700 years, although it gains a day on the Solar Year every 3225 years.
One possible fix for either standard would be to not observe A.D. 4000 as a leap year; this adjustment could wait a few thousand years for the Vernal Equinox Year.
Excellent article. Thanks!
Ping to contrast to your calendar, Segnor Of Chianti...
Maybe it’s too early in the morning for my brain, but I really can’t understand how one can go from a Thursday to a Friday by adding 10 days. Or 11.
I guess it’s just by fiat? It was just declared that for that special time, warping ahead 10 days still gave a sequential order to the days of the week? I guess it makes sense; after all if Pope Gregory didn’t do that then the historic weekly rhythm would be lost and the holy day of obligation that is Sunday would actually be a “Wednesday” or the historic “4th day of the week”.
So I guess that’s both how and the reason a ten day leap still “preserved” the historic sequence of the week. By simple fiat. So I guess I answered my own question (unless someone disagrees)

I kind of focused on the “not wanting Easter on a Jewish religious holiday” The whole idea of the thing is a permanent Passover. It is our Passover just as much as it was the Jews Passover.
I don’t care about the calendar, but I definitely want the Blood on my lintel.
Yup, you pretty much answered your own question. They wanted to preserve the days of the week (can’t goof up the Sabbath day), but needed to alter the numbering to synchronize things properly ... so one Thursday was followed by a Friday numbered 10 days into the future. Small wonder Arthur could never get the hang of Thursdays.
BTTT Calendar
Very simple. You just call the following day a Friday, which it would be anyway.
The days were still there, they were just called something else. No singularity occurred.
Just curious if Pope Gregory’s papal bull was considered “infallible”?
Quote-Ping to contrast to your calendar
I claim no ownership of our Father’s calendar!
Just to following it, wherever He leads me. And blessed to know why our Savior’s life followed it and how Israel followed it before He became flesh.
And the calendar in scripture shows any man made calendar has changed times and laws..even if they attempt to use His signs He gave us,like the sun, Moon and stars.
The fact the world runs on a Roman calendar named after a Pope in these days is just confirmation of prophetic scripture..
People would read scripture completely differently. They would understand a new way to see the 30/60/100 in the parable of the Sower in light of His Calendar..
And see how the enemy has set up a calendar that robs our Creator and Redeemer of glory and worship..appointments He taught His people(those who call themselves Jews or Israelites get it more wrong then they get it right- but scripture explains why)
It is so subtle a lie and learned as little kids that no one questions it. Praise Him He let me question it on my journey!
The difference between Passover and pope gregory Good Friday doesn’t seem like much to a follower of the Pope Gregory calendar..
But a follower of His Calendar will see quite a big difference.
A difference in the very gospel that Paul taught and how His Calendar set up Passover to be the last Work Day of His 2nd week- it is finished. Just like it was in His 1st week.
Another Jesus and another gospel.. So subtle that it can’t be seen without His help.. Just by how one tells time..or accepts the world’s premises.
Daniel 7:25 has new meaning to any who follows the biblical calendar. The calendar that only points to His Creative and Redemptive Work..
No Thor’s days..
And Satan deceives the whole world..Revelation 12:9
Quite a journey that would have people wondering if everything they were ever taught had any truth. Or just a counterfeit of Truth..
Only one way to tell. Scripture.
Great article.
I’ve always been interested in time and calendars. We sure seem to go through a lot of trouble to keep things in sync.
No, because the subject matter was not faith or morals.
It's not a definitive teaching concerning faith and morals, so the answer is "of course not".
The Gregorian calendar is not perfect, just a lot closer to astronomical truth than the Julian calendar was. A further calendar reform may make sense at some point.
