No. It did not work like that. The Act made provision for rents and debts, and people had the same number of days as they would have had the calendar not changed. The "give us our 11 days" people rioting thing is a total myth. It never actually happened; because the Act by design ensured that these inequities did not happen. There's a major part of it devoted to that. The idea of popular unrest was false political campaign propaganda by the Tories.

People who were paid daily didn't lose a thing. There were no days where they went without pay. It is people who did things *annually* that would have lost out, had the Calendar Act 1750 not explicitly made provision for them not to, as it did.

The funny part is that December 25th #JulianCalendar isn't January 6th #GregorianCalendar any more. Those islanders are living in the 19th century. It moved onto the 7th when 1900 wasn't a Gregorian leap year.

Ken Banks didn't fact check.

On the other hand, everyone would be complaining that the sunny #weather was only occurring during term time. (-:

@offenesMA @robertcasties ich habe da eine XSLT Implementation für die Umrechnung on gregorianischen, altem und neuem julianischen, hijri, osmanischem Finanzkalender und koptischem Kalender für TEI Editionen geschrieben. Die Konverter sind allerdings unabhängig von TEI: https://github.com/tillgrallert/xslt-calendar-conversion

#MizrachiChristians = Eastern Orthodox Christians, who follow the #JulianCalendar (a calendar developed under Julius Caesar); the #GregorianCalendar modified it very slightly to correct for solar drift (the Julian has 1 too many leap days every 400 years or so), but as an innovation of the Roman Catholic Church the Orthodox denominations did not adopt it.

Addendum: The #Amazigh (AKA #Berber) people use a variant of the #JulianCalendar to date traditional festivals; in this calendar, #LeapDay is added to the last month rather than the second one. Amazigh in #Morocco and #Libya celebrate traditional New Year the day after those in #Algeria, where it is a national holiday.

In 1900, Maksim Trpković revised the #JulianCalendar. Under his system, an year that yields a remainder of 0 or 400 when divided by 900 is a #LeapYear.

Milutin Milanković slightly altered this in 1923, changing the rule to years that give a remainder of 200 or 600. A mean year in this calendar is just 2 seconds off the #TropicalYear. It is used by some, but not all, #EasternOrthodox churches.

The #EasternOrthodox Churches never adopted the Gregorian calendar (except in #Finland). While Orthodox-majority countries use the Gregorian calendar for civil purposes, many still use the #JulianCalendar for religious purposes. You have probably heard about #UkrainianRefugees celebrating #Easter and #Christmas on different dates to those of #Catholics and #Protestants; this is because the Ukrainian Orthodox Church still uses the Julian Calendar (for now).

In the 17th century, #IsaacNewton recognised that the #julianCalendar was deficient but the #GregorianCalendar was too #Catholic for him. He worked on a new calendar whose mean year was just a few seconds shorter than the #TropicalYear (the mean Gregorian year is about 29 seconds longer). Newton viewed this as a feature rather than a bug, because under his system, the dates of the solstices and equinoxes would gradually drift back to those when #Jesus was alive.

A variant of the #julianCalendar was used in #Ottoman #Türkiye, in which the year began on 1 March. The newly-formed Republic of Türkiye officially adopted the Gregorian calendar in 1926 as part of #Atatürk's policy of modernisation and westernisation.

While #Britain was still using the #julianCalendar, #Catholics in #Ireland had to seek permission from the #pope to celebrate festivals on the wrong days because Catholicism was, to all intents and purposes, illegal at the time.

The #GregorianCalendar is the one used in most of the world today. It was designed by #ChristopherClavius and #AloysiusLilius, but like the #JulianCalendar, it was named after the bloke who commissioned it.

The main difference is that in the Gregorian calendar, years that are integer multiples of 400 are not leap years.

But, as we now know, the #JulianCalendar's mean year is about 11 minutes 15 seconds longer than the #TropicalYear, and by the 4th century AD, the dates of the #solstices and #equinoxes had drifted from their official dates by several days.

In the 16th century, #Pope Gregory XIII used his authority as #PontifexMaximus to reform the calendar again, because that is something #popes can do.
