I remember me that earlier time clocks had counted one hundred times per minute: 100 sec = 1 min. But the medieval people swaps onto today and into future. Look out: inch, feet, Zoll, Pfund, Doppelzentner, ounce, kg (not: Kg) as basic unit (!), HP (PferdestĂ¤rken â€žPSâ€ś). Those older mankind are using the Abacus, while it is unable to calculate mathematically, much more than counting fingers digits.

On the other hand: ÎĽC-programming cannot operate in mathematical modus. Operations are: moving â€ž0â€ś/â€žLâ€ś (lower electric potencial) or â€ž1â€ś/â€žHâ€ś (higher potencial) from memory cell to next memory cell or change the potential within a cell. Example: to multiplicate 56 with 10 cause a move every memory cell (not equal with CALC-cell!) value in one step to left and set a â€ž0â€ś in the now empty memory cell right.

The visible picture you see in a CALC-cell is not that CALC has been operated with. The procedur of calculate and depict a DATUM (Latin: take for granted, gift, item of guilty) is a very komplex task in setting leap years cause 1 year has about 365.25â€¦ days with non fixed holydays. You remember perhaps that time on one location isnâ€™t the same time on another remoted location. CALC/EXCEL does calculate only in days â€ž[DD]â€ś-unit in decimal numeral modus. CALC is than searching in a big matrix like a national calendar to find the correct weekday, holyday, month in national format, leap year type to paint that picture you will see in that cell.

To complicate this 1 year has a variable number of days so the earth is staggering surround the sun:

- 365,24219052 Tage = 365 d 5 h 48 min 45,261 s as a â€śtropical yearâ€ś,
- 365,2563604167 Tage = 365 d 6 h 9 min 9,54 s. as a â€žsidercal yearâ€ś,
- 365,259635864 Tage as a â€žabnormality yearâ€ś.

Thatâ€™s and even more declares a astronomic DATUM, which collapse of our primitive human brain by watching a beautiful coloured calendar and just as a shown CALC-area/space.

Explicit in CALC:

- nominal 365 and 366 days a year and a leap year (by using the intern calendar-matrix),
- calculating exactly with 365,2425 days a year without respect the real astronomic year so that differences are insignificant for 1 human generation.

Sorry for my â€ždeunglischâ€ś!
