 Posted: Thu, 12th Jun 2025 22:00 Post subject: Gregorian Calendar jump MDLXXXII |
|
 |
| Quote: | In many parts of the world, the dates between October 5th and October 14th, 1582, never existed on the calendar. This is because of the introduction of the Gregorian calendar by Pope Gregory XIII in 1582.
Explanation:
The Julian calendar, which was in use at the time, had accumulated a discrepancy of about 10 days with the solar year due to inaccuracies in leap year calculations. To rectify this, Pope Gregory XIII decided to skip 10 days in October 1582, thus bringing the calendar back into alignment with the seasons.
How it was implemented:
After Thursday, October 4, 1582, the next day was Friday, October 15, 1582.
This meant that the dates October 5th through 14th were simply not included in the calendar.
This calendar reform was initially adopted by Catholic countries like Spain, Portugal, and Italy, but it took time for other regions to switch over.
...
To align with the Gregorian calendar, Britain skipped 11 days in September 1752, moving from September 2nd to September 14th

Gemini AI summary
Imagine the chaos of this 10 days jump. Imagine travelling or shipping something from a Gregorian country to a Julian one.
I wonder now how historical dates, that occurred after 1582, the dates of battles or whatever interactions between Gregorian and Julian countries are presented to us at present.
As they were locally at that time?
Or as they were supposed to be by Gregorian calendar?

For this part it wouldn't be that big of an impact as we'd imagine for the time period.
Land Shipping and Sea Shipping goods was widely variable on arrival time. Not by hours but days, or weeks. And arrival time during that period only mattered on wait time, not which digit the calendar had as in "you package arrives in 2 days".
For most merchants working on that time scale of variability of the time period. Waiting roughly between 12 and 20 'sun up and down' cycles (to avoid using the word days here, actual 24 hour periods) is what really mattered for logistics.
Doesn't matter if the calendar said those 'days' ended on the 4th or the 15th. How long it actually took to move mattered more, than the number of numerical days the calender says it took.
Most peasants only worked in 'seasons' as the general measure of calendar progression. Maybe the concept of 'month' if they needed more precise timelines for crops or stock animal cycles and habits.
Why solstices/equinoxes was so special to watch for. It was used as a 'specific marker' to know the next season is starting. If they used dated numbers everyday those events wouldn't be so important to watch for, for farmers and such.
(Why WE have 4 seasons, and not 5 or 3 or 7. They are based around the timescale the average person measured on to track a year using solstices/equinoxes)
Usually only clergy and the like cares about exact date numbers, for Holidays, and special religious days and such.

Had a lovely conversation with GeminiAI on the issues of dates of Spanish Armada battles in 1588 (clearly after 1582).
Yep, good modern historians will state New Style and Old Style dates. Gregorian and Julian.
Bad historians won't bother, and depending whether they are Spanish or English, a layman reading them will get different dates for the same events.
Edit: Also some countries like Russia and Greece adopted G. C. well into 20-th century, the time of newspapers, telegraph, radio and budding air travel industry. So precise dating was kinda an issue already.

A lunisolar calendar is a type of calendar that combines the cycles of the moon and the sun. It uses the phases of the moon to define months, while also incorporating a solar year to keep the calendar aligned with the seasons. Examples of lunisolar calendars include the Chinese calendar, the Hebrew calendar, and the Hindu calendar.
Key Features of Lunisolar Calendars:
Lunar Months:
Months are based on the lunar cycle, typically lasting 29 or 30 days, corresponding to the time it takes for the moon to go through its phases (new moon to new moon).
Solar Year:
The calendar is adjusted to align with the solar year, which is the time it takes for the Earth to orbit the sun. This is usually achieved by adding an extra month (an intercalary month) periodically.
Intercalation:
The process of adding an extra month (leap month) to the calendar to account for the difference between the lunar and solar years. This ensures that festivals and agricultural events occur during the appropriate seasons.
Examples:
Common examples include the Chinese calendar, the Hebrew calendar, and the Hindu calendar.
Flexibility:
Lunisolar calendars can be adapted to various cultural and agricultural needs, often incorporating observations of natural phenomena tied to both lunar and solar cycles |
