Eftersom jag forskar om tid fastnar jag med jämna mellanrum för nördiga detaljer typ skiftet mellan den julianska och gregorianska kalendern. Jag beslöt mig för att se vad min dator hade att säga om saken och bläddrade tillbaka till 1582 då flera länder bytte kalender. Resultatet, ett mycket kort oktober, se du ovan
Det var bara ett fåtal länder som bytte kalander 1582, så jag antar att datorn kompromissat för att så många datum ska stämma på så många platser som möjligt. Sverige bytte exempelvis inte förrän 1753 och hann däremellan ha en helt egen kalender samt världshistoriens enda 30 februari.

What happened on October 6, 1582
ChatGPT
On October 6, 1582, nothing significant occurred in history. This date falls within the period when the Gregorian calendar was being implemented, and in some regions that adopted the new calendar, October 5 was followed by October 15, 1582, to align with the adjustments made by Pope Gregory XIII’s reform. Therefore, October 6, 1582, was one of the ten days skipped in countries transitioning from the Julian calendar to the Gregorian calendar. As a result, no events of historical note are recorded for this date.

What happened February 30 1712
ChatGPT
February 30, 1712, did not exist in the Gregorian calendar or any other widely used calendar system. The Gregorian calendar, introduced in 1582, follows a standard structure with months of fixed lengths. February, in particular, has either 28 or 29 days during a leap year.
February 30 has never been a valid date in any calendar system. Its mention typically refers to mistakes, calendar reforms, or misunderstandings rather than an actual occurrence.

February 30, 1712 actually existed in Sweden which switched from the Swedish calendar back to the Julian
ChatGPT
You’re correct. In 1712, Sweden was using the Julian calendar and had planned to switch to the Gregorian calendar, which was already adopted by many other European countries. As part of the transition, Sweden decided to have a ”double” leap year by adding an extra day in February. This resulted in February having 30 days in the Swedish calendar for that year.
This adjustment was made to align Sweden’s calendar with the Gregorian calendar used by neighboring countries. Eventually, in 1753, Sweden officially transitioned to the Gregorian calendar like the rest of Europe, but during the interim period, unique adjustments like the extended February occurred to bridge the gap between the two calendar systems.
