If a `%3' text is not succeeded by a `%4' text on the line, Gcal automatically inserts such a `%4' text at the end of the line.

File: gcal.info, Node: Date variables, Prev: Special macro texts, Up: Resource file Date variables -------------- Gcal respects *global* and/or *local* date variables (*note `--date-variable=ARG': Date warning options.). This means up to *25* user defined date variables can be set and referenced during program execution. The name of a date variable DVAR is a single alphabetic character (except the `e' character, which is internally reserved for the Easter Sunday's date and unassignable/unoperatable) followed by the assignment operator character `=' and the numerical values of month and day MMDD this variable has to store or the reference to another date variable, e.g.: a=1127 b=05fr4 c=a Only local date variables can store dynamic dates given in the `MMWWWN' or `*d|wN[WWW]' format, e.g.: a=03su2 b=JunMon9 x=*d10 y=*d10fri z=*w3Su which means, date variable A stores the date of second Sunday in March and B stores date of last Monday in June. The date variable X stores the date of the 10'th absolute day of the year (== 10'th January). Y stores the date of the 10'th Friday of the year, and the assignment to Z is the date of the Sunday, which occurs in the 3'rd week of the year. *Caution:* These kinds of assignments to date variables are *only* computed correctly in simple year bounds, which means during a current year, not in fixed dates shown after the current year has changed, e.g. in `fiscal years'. Date variables which are defined in a resource file are always local and only respected in this specific file and that file, which is included by it. This means for the included file that *all* local variables of the caller are visible. The included file itself may define its own local variables in its own name-space, which are not exported to caller on return. All other definitions of date variables (in command line, environment variable or response file) are always global. If a resource file line contains a reference of a date variable, which is not locally defined in that file, Gcal will try to use the global values held by this variable. If this fails because no global definition of this date variable is given, Gcal will not process this line. If the simple `--debug' respectively `--debug=internal' option is given, warning messages for each undefined date variable will be shown (*note `--debug=internal': Global options.). If the `--debug=abort' option is given, Gcal will abort program execution when the first undefined global date variable reference occurs. For more information, see *Note `--debug=abort': Global options. Only advanced users should apply the `--export-local-date-variables' option, which affects that the actual incarnation of a local date variable - which was previously defined in a resource file and not in an included file - is being exported to further resource files instead of using its global value in case that date variable isn't locally defined in that further resource file. *Note Include statements::. But be aware, the use of this option could create unwanted results, because the order of processing the resource files is an important entity in managing the `--export-local-date-variables' option, so it's not recommended using it. You, the user, must know exactly what you're doing when applying this option; *you are expressively warned now!* Some basic operations can be performed on date variables. These are: `DVAR++' Simple incrementation by one day. `DVAR--' Simple decrementation by one day. `DVAR+=N' Addition of a constant numeric day factor N. `DVAR-=N' Subtraction of a constant numeric day factor N. The scope of the operations which are done on a local date variable, is that resource or include file, where the local date variable is defined. If operations on a global date variable are performed in a resource file or that file which is included by it, these operations are only valid in that specific file (they are done locally), not in further resource files processed. This means the initial values of global date variables are always restored if the resource file changes. Please note that each date variable assignment/operation must be given on a single line in the resource file.

The aim of all these calendars was to harmonize the cycles of the moon and the sun. During Julius Caesar's reign, January was falling in autumn so he ordered Sosigenes to make changes to the calendar. He added 90 days to the year 46 B.C. to make up for the seasonal drift and adjusted the lengths of the months similarly as we know them to be today. He introduced the leap year by adding one day to February every four years. For the present, the leap year regulation was made in the way, that all four years after the 23'rd day in February a leap day was layed in, so the 24'th February occurred twice. The use of the leap year was an improvement but not entirely accurate. But in the later years, the leap rule was used in the wrong way so that the emperor Augustus corrected the errors in the year 8 B.C. A curious sequel happened on this occasion. Because Augustus reacted with great jealousy to all things previously made and propagated by Julius Caesar, he didn't like Caesar's name in the calendar, namely the today's month of *July*. Offhandedly he named another month to himself and so the month name *August* arose. Furthermore, Augustus did not tolerate the fact, that his month of birth (the August) was shorter than Caesar's month in the sense of the periodical sequence of months with 30 and 31 days. Consequently, the month of August got 31 days, too. By reason of this, the number of days in February were reduced to 28 and 29 days, respectively. This calendar is well known under the term "Julian calendar" and is based on a plain solar year. The nominal length of a solar year (respectively a so-called tropical year) is 365 days, 5 hours, 48 minutes, and 46 seconds. One 366-day year every four years equates to an average Julian year of 365 days and 6 hours, consequently to 365.25 days. This means every four years, an error of 44 minutes, 56 seconds was accumulated by this kind of calendar calculation. Because of this counting method, the length of the years becomes a bit too long, by more than 11 minutes. By the 16'th century, the vernal equinox occurred around March 11, rather than March 21, by reason of an accumulated error of ten days. The feast of Easter shifted away more and more from the habitual vernal date, which must have always been celebrated on an earlier date. So Pope Gregory XIII introduced the new style calendar in 1582. Thursday, the 4'th October 1582 was followed by Friday, the 15'th October, by suppressing the ten days between both dates. Moreover, he ordained that years ending in hundreds should not be leap years unless they are divisible by 400. Incidentally, the "Gregorian reform" compensates by 72 hours (3 days) every 400 years. The actual excess accumulated is 74 hours, 53 minutes and 20 seconds. The error of 2 hours, 53 minutes and 20 seconds every 400 years accumulates to one day in 3323 years. Thereby the Gregorian year has an average length of 365.2425 days. But this "Gregorian calendar" was accepted very slowly by others. Catholic countries adopted the Gregorian calendar almost immediately. Most Protestant countries on the Continent adopted the new calendar around 1700. England and the American colonies changed in 1752, by act of Parliament. Orthodox Christian countries adopted the Gregorian calendar later. Russia was the last European country to do so, after the communist revolution of 1917. As a result, the USSR celebrates the October Revolution (happened on October 25, 1917) in the old style calendar on November 7. Up to now, China was the last country to change over its chronology, conforming with the Gregorian calendar in 1949. The era of a world wide uniform calendar is already part of history today. The Iran returned to the traditional Mohammedian moon calendar in 1978 after removal of the Schah reign. There are some efforts to improve our actually valid Gregorian calendar. Its disadvantages are the fact, that an appointed day is not always on the same week day. Besides, the month lengths are not equal and the holidays, which have relations to the feast of Easter are moved within the calendar from one year to another. A very sophisticated suggestion was proposed by the United Nations, but the international establishment of this suggestions has failed, since it was resisted by some countries as well as the churchs.
