**Biorhythmic divination**

Biorhythmic divination is a divination by means of biorhythms.

**Origin**

The theory of biorhythms claims that one's life is affected by rhythmic biological cycles, and seeks to make predictions regarding these cycles and the personal ease of carrying out tasks related to the cycles. These inherent rhythms are said to control or initiate various biological processes and are classically composed of three cyclic rhythms that are said to govern human behavior and demonstrate innate periodicity in natural physiological change: the physical, the emotional, and the intellectual (or mental) cycles. Others claim there are additional rhythms, some of which may be combinations of the three primary cycles. Some proponents think that biorhythms may be potentially related to bioelectricity and its interactions in the body.

**Basic Rhythm Details:

memory or recall

communication

**Methods**

It is possible to calculate one's biorhythm using one's birthdate. These calculations will result in a graph showing three curves, each representing one of the three cycles.

Take the current year and subtract 1900 (e.g. 2006 – 1900 = 106). This number is further referred to as the present year. Please note that if you wish to calculate the three cycles of a month in another year, you should work with that year and not the current one.

Take your birth year and subtract 1900 (e.g. 1976 – 1900 = 76). This number is further referred to as your birth year.

Take the number representing the current month (e.g. 1 for January). If this number is smaller than 3, then add 10 to the number representing the current month. If this is not the case, subtract 2 from the number representing the current month (e.g. 1 represents January. 1 is smaller than 3, thus we add 10 to 1, which results in 11). This number is further referred to as the number representing the current month. Please note that if you wish to calculate the three cycles of another month, you should work with that month and not the current one.

Take the present year and subtract 1 if the number representing the current month is smaller than 3. Otherwise, do nothing (e.g. the number representing the current month is 2 and the present year is 106. 2 is smaller than 3, so we subtract 1 from 106, which gives us a new present year of 105). We call the resulting number the present year from now on.

Now we will calculate the first number, which is done like this: multiply the number of the present year by 365. Add the result of multiplying the number representing the current month by 28. Add the result of multiplying the number representing the current month by 2,59. Subtract 2. Add the result of dividing the number representing the current month by 4. Subtract the result of dividing the number representing the current month by 100. Add the current day, further referred to as the current day. The result of this long formula is called, as previously mentioned, the first number. Note that after every step in calculating the first number, the result ought to be rounded (towards the floor if the 10ths are smaller than 5 and towards the ceiling if otherwise).

Take the number representing your month of birth (e.g. 3). If this number is smaller than 3, then add 10 to the number representing the current month. If this is not the case, subtract 2 from the number representing the current month (e.g. 3 represents March. 3 is equal to, but not smaller than, 3 thus we subtract 2 from 3, which results in 1). This number is further referred to as the number representing your month of birth.

Take your birth year and subtract 1 if the number representing your month of birth is smaller than 3. Otherwise, do nothing (e.g. the number representing your month of birth is 1 and your birth year is 76. 1 is smaller than 3, so we subtract 1 from 76, which gives us a new your birth year of 75). We call the resulting number the present year from now on.

We will now calculate the second number, which is done like this: multiply your birth year by 365. Add the result of multiplying the number representing your month of birth by 28. Add the result of multiplying the number representing your month of birth by 2,59. Subtract 2. Add the result of dividing your birth year by 4. Add the result of dividing your birth year by 400. Subtract the result of dividing your birth year by 100. Add your day of birth, further referred to as your day of birth. Note that after every step in calculating the second number, the result ought to be rounded (towards the floor if the 10ths are smaller than 5 and towards the ceiling if otherwise).

Subtract the second number from the first number. The result will be referred to as the third number.

With the third number, we can finally calculate the status of every cycle for every day of the month.

For the physical cycle, multiply 2 with pi. Multiply this with the result of adding the third number to the current day of the month and subtracting 1. Divide this by 23. The sine of the result of that is the number representing the state of the physical cycle of whichever current day of the month you chose.

For the emotional cycle, do the same as for the physical cycle with the only difference being you should divide by 28 and not 23 like for the physical cycle.

For the intellectual cycle, do the same as for the physical cycle, with the only difference being you should divide by 33 and not 23 like for the physical cycle.
