The furlong–firkin–fortnight (FFF) system is a humorous system of units based on unusual or impractical measurements. The length unit of the system is the furlong , the mass unit is the mass of a firkin of water, and the time unit is the fortnight .
A calendrical calculation is a calculation concerning calendar dates. Calendrical calculations can be considered an area of applied mathematics. Some examples of calendrical calculations: Converting a Julian or Gregorian calendar date to its Julian day number and vice versa (see § Julian day number calculation within that article for details).
A fortnight is a unit of time equal to 14 days (two weeks). The word derives from the Old English term fēowertīene niht , meaning " fourteen nights " (or "fourteen days", since the Anglo-Saxons counted by nights).
Celestial sphere-based: as in sidereal time, where the apparent movement of the stars and constellations across the sky is used to calculate the length of a year. These units do not have a consistent relationship with each other and require intercalation. For example, the year cannot be divided into twelve 28-day months since 12 times 28 is 336 ...
In the 7-day fortnight plan or 2-3-2 plan, employees work their allotted hours within 7 days rather than 10 in a fortnight, i.e. fourteen days and nights. Therefore, 41 hours per week equate to 82 hours per fortnight, which is worked in seven days, at 11–12 hours per shift.
According to the "Date" system in Knuth's article, which substitutes a 10-clarke "mingo" for a month and a 100-clarke "cowznofski", for a year, the date of October 29, 2007 is rendered as "Cal 7, 201 C. M." (for Cowznofsko Madi, or "in the Cowznofski of our MAD"). The dates are calculated from October 1, 1952, the date MAD was first published.
The doomsday's anchor day calculation is effectively calculating the number of days between any given date in the base year and the same date in the current year, then taking the remainder modulo 7. When both dates come after the leap day (if any), the difference is just 365y + y / 4 (rounded down). But 365 equals 52 × 7 + 1, so after ...
The basic approach of nearly all of the methods to calculate the day of the week begins by starting from an "anchor date": a known pair (such as 1 January 1800 as a Wednesday), determining the number of days between the known day and the day that you are trying to determine, and using arithmetic modulo 7 to find a new numerical day of the week.
