TIL George Washington was born in Virginia on February 11, 1731 according to the then-used Julian calendar. In 1752, however, Britain and all its colonies adopted the Gregorian calendar which moved Washington's birthday a year and 11 days to February 22, 1732.

What if the countries that use the Gregorian and/or Julian Calendars used the Jewish Calendar instead?
They still become Christian. I suppose this means there would have to be 1 difference between TTL's Christian Calendar and OTL's Jewish calendar. That TTL's christian calendar will start at the birth or death of Christ

Thinking about all the couples who weren't prepared for Valentine's day in 1918. Not only was it in the midst of the world war and a revolution, but they lost two weeks to prepare!

When we talk about events in years before 1582, do we say the date as it was said in the Julian calendar, or is it calculated backwards to be in Gregorian?
Like like take the Battle of Hastings, October 14th 1066. Was that October 16 in Gregorian terms, or October 16 in Julian terms, which would've been different dates

114 years ago, the October Revolution began (November 6th to 7th in the Gregorian Calendar, October 24th to 25th in the Julian calendar). This occurred after the Bourgeois Democratic revolution in February and established a government led by the Bolsheviks and Left SRs.

The modern-day Gregorian calendar was introduced in 1582, but for centuries many European countries stuck to the Julian calendar, which was 10+ days behind the Gregorian. Did the difference in dates cause confusion in matters of international travel, trade, and communication?

Christmas and Easter aren't based on pagan festivals. Episode 3 takes a look at two modern theories on the origins of the traditional dates of Christmas and Easter. Also, a digression on the traditional dates of the equinoxes and solstices in the Julian calendar.

Iโm not trying to move goal posts but what if the FoF are still using our Julian calendar? (sorry i accidentally deleted the original)
Since 1582 weโve been using the Gregorian calendar established by Pope Gregory XIII. Before that we were using Julian Calendar (established by Julius Caesar) for almost 1600 years.
If these Aliens have been around for thousands of years who knows what human calendar they adhere to? Therefore if nothing happens on July 18, i will also keep my eyes peeled on July 31st which translates to July 18 on the Julian calendar.
Basically i will be on edge this entire month.

How would I determine exact dates according to the pre-Julian Roman Calendar?
I would like to be able to do this in general, but I do need two specific dates.
What I need is the date July 17, 187 BC according to the Roman Calendar used at that time. I also need to know what date they would have considered to be exactly one year prior that on both their calendar and ours.
I hope that makes sense. Here are the two questions reframed:
On July 17, 187 BC, what would a Roman have said the date was?
What would one year prior to that date, according to that calendar, have been?

Fuck the Julian/Gregorian Calendar
Note: The Gregorian calendar is just a less ass version of the Julian calendar -- it's fine tuned the amount of leap years.
First off, the issue of the months of August and July, which were added due to Caesar Augustus' ego. This throws off the pattern of (Sept)ember : 7, (Oct)ober : 8, (No)vember : 9, (Dec)ember : 10 by adding two to all of the following numbers. February has too few days and the 31-30 alternating pattern gets flipped at one point.
This makes no mathematical sense so it is difficult to deal with as a programmer. (Although I admit every programming language has systems to handle dates)
A better system would have the days of a month be somewhat consistent. Admittedly, this is difficult since 365 has a prime factorization of 5 and 73, but a similar (yet consistent) system to the 31-30 alternation could be set up with the months having 36 days or 37. The total number of months would be a clean 10 (we would omit July and August). The weeks should be 9 days so they can be somewhat evenly divided by the months and for the months with 37 days we could simply add another day to the fourth week. And for leap years, we can keep Pope Gregory's rule for when to have them, but we should always tag the 366th day at the end of the year. (This might give us an extra day off on the holiday season). Lastly, new years should be on a date with some astronomical significance, like a solstice or equinox. I think the winter solstice would be good.
Alright rant over. I just needed to vent about how our calendar is ass and propose a solutions no one will ever use.

Did the Celts have their own calendar system before the introduction of the Julian Calendar to Roman Gaul in the 2nd Century? If so, can any information on it be pieced together?
Dating back to the 2nd Century CE, The Gaulish Coligny calendar is the oldest discovered Celtic solar-lunar ritual calendar. However, the astrological format of the Coligny calendar speaks to a sophistication, particularly focused on a careful significance placed upon the cycles of the moon, that may represent a more complicated system that the Julian calendar was being melded with during it's imposed introduction into Roman Gaul.
> The Coligny Calendar is an attempt to reconcile the cycles of the moon and sun, as is the modern Gregorian calendar. However, the Coligny calendar considers the phases of the moon to be important, and each month always begins with the same moon phase. The calendar uses a mathematical arrangement to keep a normal 12 month calendar in sync with the moon and keeps the whole system in sync by adding an intercalary month every 2+1โ2 years. The Coligny calendar registers a five-year cycle of 62 lunar months, divided into a "bright" and a "dark" fortnight (or half a moon cycle) each. The months were possibly taken to begin on the new moon, and a 13th intercalary month was added every two and a half years to align the lunations with the solar year.
> The astronomical format of the calendar year that the Coligny calendar represents may well be far older, as calendars are usually even more conservative than rites and cults. The date of its inception is unknown, but correspondences of Insular Celtic and Continental Celtic calendars suggest that some early form may date to Proto-Celtic times, roughly 800 B.C. The Coligny calendar achieves a complex synchronisation of the solar and lunar months. Whether it does this for philosophical or practical reasons, it points to a considerable degree of sophistication.
What do we know about this mysterious lunar system that may have existed before the introduction of the Julian calendar? If we have no surviving evidence, are there other calendar systems that we can look to to get an idea of how it may have operated?
