Is there some #genealogy software that does dates correctly?

E.g. user enters dates as recorded by authorities, but lets assume that a person moved from #Norway / #Denmark to Sweden in 1730. The records in #Norway / #Denmark would be in #GregorianCalendar, and the Swedish dates would be in #JulianCalendar. Assume that there are dates from the first decade of 1700s, when the #SwedishTransitionalCalendar was in operation and subsequently paused and abandoned, resulting in that February 30, 1712 is a valid date in #Sweden(!), and the other days being one day off from the Julian calendar.

Basically, all software seems to flag the date of 1712-02-30 as invalid, because it is impossible to specify the correct calendar.

And lets not get started about age calculations before new-year was moved to first of January (in many places this was well before the #Gregorian calendar introduction).

#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.

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.

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.
