According to German Historian Heribert Illig, the year is actually 1720, the Gregorian calendar is a lie, and a chunk of Middle Ages was completely made up. He actually claims to have archaeological evidence to support his case.
Phantom Time Hypothesis
According to the All That Is Interesting, in 1991, Illig proposed his theory, aptly called the Phantom Time Hypothesis. He claims there was conspiracy entered into back in 1000 AD to change the dating system by three world rulers.
Illig claims that Pope Sylvester II, Holy Roman Emperor Otto III, and Byzantine Emperor Constantine VII all got together and changed the calendar to make it seem as if Otto had begun his reign in the millennial year of 1000 AD, rather than 996. The reason being that 1000 sounded a lot more meaningful than 996 considering AD stands for “anno domini,” or, “the year of the Lord.”
“An extra 297 years were added to history”
These all years actually not happened. Mathematical discrepancies between the Julian and Gregorian calendars further complicates things. The Julian calendar says that a full year is 365.25 days long, whereas the Gregorian calendar (the one we use now), says it’s actually 11 minutes shorter than that.
Did the Early Middle Ages Really Exist?
In 1995, Dr Hans-Ulrich Niemitz published a paper in which he wrote, “Between Antiquity (1 AD) and the Renaissance (1500 AD) historians count approximately 300 years too many in their chronology,” Niemitz wrote. “In other words: the Roman emperor Augustus really lived 1700 years ago instead of the conventionally assumed 2000 years.”
