... Gregory dropped 10 days to bring the calendar back into synchronisation with the seasons. Accordingly, when the new calendar was put in use, the error accumulated in the 13 centuries since the Council of Nicaea was corrected by a deletion of ten days. The Julian calendar day Thursday, 4 October 1582 was followed by the first day of the Gregorian calendar, Friday, 15 October 1582 (the cycle of weekdays was not affected) ...

... The reform was adopted initially by the Catholic countries of Europe. Protestants and Eastern Orthodox countries continued to use the traditional Julian calendar and adopted the Gregorian reform after a time, for the sake of convenience in international trade. The last European country to adopt the reform was Greece, as late as 1923 ... Britain and the British Empire (including the eastern part of what is now the United States) adopted the Gregorian calendar in 1752, by which time it was necessary to correct by 11 days. Wednesday, 2 September 1752, was followed by Thursday, 14 September 1752. Claims that rioters demanded 'Give us our eleven days' grew out of a misinterpretation of a painting by William Hogarth:

However, a picture will tell more than simple words, will be possible to understand on several levels.

The transition period between the hairy back of the head of Ku and his alighted face needed only 4 right ascension days, and 4 calendar days was also the difference between 52 weeks (= 4 * 91 days) and 360 days.

Strangely the front of the head of the god (Ku) - at Sheratan (β, female sign) - came before α (Hamal). A woman should always go a few paces behind her man.

But if there were 4 days from the December solstice to Christmas Eve and 4 days from the June solstice to St John's Day, then there surely ought to be 4 days also from an equinox to its corresponding cardinal calendar day:

The central Rakau element was standing there also at the equinoxes, although at another time angle in the night. And to the left of Rakau there was a more profound Mother Earth (as a Turtle) glyph. The Rakau (the α male) was surrounded by 10 'feathers' (supporters) and separated from the Nativity place (central ceremonial ground) by 4 days (2 down and 2 up), and we could think 21 + 4 = 25 (Christmas Eve, Julian spring equinox, etc).

The front of the head, his Face (Mata), ought to mean the place where light returned. But this could not be observed until at least 16 days after Sun had been there. Counting feathers we will find 5 + (2 + 2) + 4 = 7 + 6 = 13. And then we could add the 3 basic elements of the glyph and get 16:
