Daily rhythms & self-reflection
Every day has a shape.

About Biosoft Global
Three rhythms, followed for 45 years.
It began as one long piece of work: decades spent computing and tracking the physical, emotional and intellectual cycles across hundreds of thousands of recorded days. BioCalendar is where it lives now. It does not diagnose, forecast or promise. It tells you where your three rhythms sit today, in plain words, and lets you decide what to make of it.

Biorhythm Journal
Nature keeps time.
Biorhythms are based upon the fact that many things within nature happen in cycles: things that occur and recur. Planets orbiting the sun, the migration of birds and fish, the tides, the phases of the moon. The list is almost endless.
twice a day
The tides
The sea rises and falls about every twelve hours and twenty-five minutes, pulled by the moon and the sun.
turns once a day
The night sky
As the earth turns, the stars wheel around the pole and come back to the same place a day later.
every 29½ days
The moon
From new to full and back to new again in about twenty-nine and a half days.
once a year
Migration
Cranes, swallows and salmon travel the same routes at the same season, year after year.
And in you, three more.
BioCalendar follows three such cycles in a person, each on its own fixed period, and reads the day by where all three sit at once. Every cycle passes through the same eight states in turn, and the states have names.
a 23-day cycle
Physical
Energy, strength, endurance and physical resilience.
a 28-day cycle
Emotional
Mood, creativity, sensitivity and emotional steadiness.
a 33-day cycle
Intellectual
Logic, memory, concentration and clear thinking.
Reading a day
Eight states, three hands.
Every cycle is a loop through the same eight states, in the same order. On the dial, the days above the midline sit out on the right and the days below sit in on the left. Each cycle has a hand; they start together on the day of birth and drift apart, and a day is read where the three point.

Together, the three states choose one of 512 written readings for the day. The app shows you yours.
The hands only point to the top together again after 21,252 days, about 58 years and two months.
- c, Critical, rising: Day 1 of the cycle, crossing the midline upward. Critical days are when the cycle changes direction, and are traditionally read as unsettled rather than bad.
- +, Rising: Between the rising critical day and the high. Positive and climbing.
- H, High: The peak of the cycle — its strongest point.
- #, Falling from high: Past the peak and heading down, but still above the midline.
- C, Critical, falling: The cycle crossing the midline downward, part-way through. Also a change of direction.
- -, Falling: Below the midline and still descending, towards the low.
- L, Low: The trough of the cycle — its weakest point.
- *, Recharging: Past the low and climbing back towards the midline. Biorhythm writers call this the recharging phase.
