I tried this component out and unfortunately the calculations are not completely correct. For instance - the eggs are ferile only within 24 hours after ovulation bit this calender shows fertility possibility 48 hours after. And the input field for menstruation length does not affect the calculation. It should make significant difference in ehat day the woman in ovulating. It not possible to use other language than english since there is no language file. I transleted directly in the php-file.
But it has great possibilities to become a good component. It is simple, easy to use, easy to understand and have nice graphics.

Thanks for your comments,
Concerning the ovulation, it is the probability of presence of egg and not the egg life time.
Concerning the menstruation length, yes it does not affect the calculation and this is a true because you calculate the ovulation and fertility date based on the next expected menstruation day minus 14 days. The menstruation day affect only the chart for none sexual days.
Thank you for your feedback.
