How To Calculate The Fertile with KBA Calendar System
Before using this method, of course, married couples must know the fertile period. Cycles in each woman's fertile period is not the same. For that we need the observation of at least 6 times of the menstrual cycle. Here's how to find and calculate the fertile period:

When regular menstrual cycles (28 days):
* The first day of the menstrual cycle is calculated as the day-to-1
* The fertile is the day of the 12th until the 16th day of the menstrual cycle

example:
A wife got my period started on 2 October. October 2 is counted as day 1. So the 12th day falls on October 13th and 16th day falls on October 17th. So the fertile period is from October 12 until October 17th. On these dates may not be husband and wife have sex with wife (relations agency.) because if the wife violated the possibility of pregnancy is very big.

If an irregular menstrual cycle:
Record number of days in a menstrual cycle for 6 months (6 cycles). The menstrual cycle is calculated from the first day of menstruation at this time until the first day of next menstruation.
Shortest number of days in menstrual cycle minus 6 times 18. This count determines the first day of fertile period. The number of the longest day for 6 menstrual cycles minus 11. This count determines the last day of fertile period.

Formulas:
The first day of the fertile period = Number of days the shortest - 18
The last day of fertile period = Number of days the longest - 11
Example:
A wife got my period with the state: the shortest cycle of 26 days and the longest cycle of 32 days (beginning the first day of menstruation until the next menstruation).
The calculations are: 26-18 = 8 and 32-11 = 21. so the fertile period is to begin day-to-8 to the 21 from the first day of menstruation. At this time bersanggama.setelah spouses should not be allowed to pass from the new.

How To Calculate The Infertile with KBA Calendar System
How to calculate infertility is fairly easy. First of all, for 12 months, long menstrual cycles were recorded. Menstrual cycle is calculated starting from the first day of menstruation until the day before the first day of next menstruation. Of note will be seen whether or not regular menstrual cycles. For those who have irregular menstrual cycles, please note the number of days the shortest period and the number of days the longest period.
Then, after the menstrual cycle record is obtained, stay longer count infertility. Counting time is not fertile before ovulation by subtracting the shortest period with 21. 21 Figures derived from the sum of the egg maturation time (16 days) and the ability of live sperm cells in the uterus (5 days). For example, the shortest period is 28 days, the period is not fertile before ovulation is the first day until the seventh day (28-21). If the shortest period of 25 days, then infertility is the first day to the fourth (25-21).
Calculation of infertility after ovulation did not differ significantly. The difference is only used during menstrual periods and rate reduction. Infertility after ovulation is calculated by subtracting the longest period minus 9. Number 9 is obtained from the reduction in egg maturation shortest time (11 days) with an egg cell survival (20 days). For example, the longest period is 28 days, the period of infertility after ovulation from day 19 to the next menstruation. If the longest period of 30 days, then infertility starting day 21 until the next menstruation.
