G.2.1.10 Biorhythm %?[date] special texts

Gcal is able to create a biorhythm for any specified date of birth. The created text shows the three standard biorhythm cycles, and that are the 28 day emotional cycle, the 33 day intellectual cycle, and the 23 day physical cycle. The emotional cycle governs sensibility, nerves, moodiness, and creative ability. The intellectual cycle reflects intelligence, memory, mental alertness, and reasoning power. The physical cycle represents physical strength, endurance, energy and resistance. All cycles start in the zero point at the date of birth and swing like sine curves between their positive and negative maximum values. The periods above the zero point show the days of full vitality and efficiency while the periods below the zero point indicate days of reduced efficiency. The biorhythm is implemented for entertaining purposes only! It is up to the user to interpret the biorhythm texts.

Gcal counts critical days, positive likewise negative days. Critical days are those days in which one or more of the biological cycles crosses the zero point. At that time, one's system is said to be in a state of flux and it may be desirable to exhibit caution. Positive days are those days in which one or more of the biological cycles have a positive maximum value. At that time, one's system is said to be in a raised state. Negative days are those days in which one or more of the biological cycles have a negative maximum value. At that time, one's system is said to be in a lessen state.

The following biorhythm %?[date] special texts are respected:

%,[date]
Is replaced by the biorhythm text of the current day of year, e.g.:
The text ‘%,19620921 will be expanded to
==> ‘1! 0+ 0- , Emo=+022%- Int=-091%+ Phy=-014%-, in case the actual system date is the 12th December 1996.

The preceding example shows the calculated biorhythm expressed as a series of values for a person born in 1962, September 21st. The constructed text consists of two parts, and that is on the one hand a triplet of total values which indicate the critical, positive and negative day. And on the other hand a triplet of values which indicate the emotional, intellectual and physical cycle.

In the first triplet of total values, a ‘!’ suffix means a critical day, a ‘+’ indicates a positive day, and a ‘-’ suffix marks a negative day.

In the second triplet of values, each single cycle percent value consists of a leading positive or negative sign that tells something about the distance of this value to the zero point, and a trailing character that tells something about the state of each cycle. A trailing ‘+’ character marks a waxing phase, a ‘-’ suffix means a waning phase, and a ‘@’ indicates the maximum value of a phase.

%;[date]
Is replaced by the biorhythm text graphics of the current day of year, e.g.:
The text ‘%;19620921 will be expanded to
==> ‘0-  I               P 1   E                +0, in case the actual system date is the 12th December 1996.

The preceding example shows the calculated biorhythm expressed as a text graphics line for a person born in 1962, September 21st. The constructed line is a bar with a negative and positive axis of adjustable length (see Fixed date option --biorhythm-axis=number), which left margin is represented by the total value of the negative days (the ‘0-’ in this case), and which right margin is represented by the total value of the positive days (the ‘+0’ in this case). The zero point of the co-ordinate is represented by the total value of the critical days, which is the ‘1’ in this case. The emotional, intellectual and the physical phase value is accordingly placed in scaled manner on this bar, and that by using the initial letter of the cycle in each case (‘E’, ‘I’ and ‘P’). Coincidental phase values are marked by a ‘@’ character.
