SUMMARY
It is possible to use Microsoft Excel to create a biorhythm chart. Abiorhythm chart tracks the physical, emotional, and intellectual cycles ofa person over a 29-day period. These three cycles are further broken downto the following day periods:
   Physical:      23-day period   Emotional:     28-day period   Intellectual:  33-day period				
MORE INFORMATION
On a chart, these three cycles duplicate a sine wave pattern. Days thatfall above the X-axis are said to be good days, and conversely, days thatfall below the X-axis are said to be bad. To chart a biorhythm, followthese steps:
  1. Enter the following data in a worksheet:
            A1: Name:           B1:                    C1:        A2: Birth date:     B2:                    C2:        A3: Today's Date:   B3:                    C3:        A4:                 B4:                    C4:        A5:                 B5: Days Elapsed       C5:        A6: Period          B6: Since Birth Date   C6: Date        A7:                 B7:                    C7:        A8:                 B8:                    C8:					
  2. In cell B3, type the following formula to return the current date:
    B3: =TODAY()
    In cell B2, type the date of birth of the person whose biorhythm is being charted. In cell B1, type the name.
  3. To create a series that will represent the days in each 29-day period, type the following values into the following cells:
    A7: -14
    A8: -13
    Select cells A7:A8. Use the fill handle to fill the cells down through cells A9:A35.
  4. In cell B7, type the following formula to calculate the number of days that have elapsed between the day in the 29-day period and the birth date:
    B7: =$B$3+A7-$B$2
    With cell B7 selected, use the fill handle to fill the formula down through cell B35.
  5. To create the dates that fall in the 29-day period, enter the following formula in cell C7, and then fill it down to cell C35:
    C7: =$B$3+A7
  6. Type the following data in the worksheet:
    D6: Physical
    D7: =SIN(MOD($B7,23)*2*PI()/23)

    E6: Emotional
    E7: =SIN(MOD($B7,28)*2*PI()/28)

    F6: Intellectual
    F7: =SIN(MOD($B7,33)*2*PI()/33)
    Select cells D7:F7 and fill the formulas down through cells D35:F35.
  7. To create the chart do the following:
