An appearance factor of days (`.n') is specified by a `.' character and must trail the day field -- which must have a concrete value in a date part of a Gcal resource file and has not been set to a zero value -- respectively either lead or trail a repetition factor of days. Except fixed dates which occur only on a definite weekday and are not specified by using a range of days, like `199600mon Every Monday 1996', such an appearance factor may be specified in all possible codings of date parts of a Gcal resource file. This factor may be specified with each single element of lists of days, but in a range of days, this factor may trail only the final day of the range. Well, the use of such an appearance factor is only helpful if it is either given in a range of days, or if it is given together with a repetition factor.
This factor may have values in range 1...999. Fixed dates will be ignored if the factor takes values greater than the real difference between the date of the occurrence of the fixed date and the last day of the year, respectively the end of the period, for which the fixed dates shall either be produced or respected.
An appearance factor of days is used to define a concrete displacement of recurrent fixed dates. Assuming a fixed date shall always occur on the 15th day in every month of the year 1996 and covers a period of seven days (inclusive the 15th itself), but shall only be respected every third day (i.e. two days have to be skipped at a time) within this period, e.g. `Training-college', one solution would be on the one hand a fixed date entry in the resource file for the 15th of the month, for the 18th and for the 21st of the month, which would be a total of three entries in the resource file for such a fixed date (42).
On the other hand, this expense can be reduced to a total of only one entry in the resource file by using an appearance factor of days, which is likewise valid for the 15th, the 18th and the 21st in every month, namely on the one hand by the use of a repetition factor
19960015:7.3 Training-college
or on the other hand by the use of a range of days
19960015#21.3 Training-college
The use of appearance factors of days in the date part is permitted as follows:
