In brief: You don't

Calculators make assumptions that everybody ovulates and that everybody has periods every month.
However, this may not necessarily be the case. Calculator will just give you an ovulation date 2 weeks prior to your menses. To be certain that you actually ovulate, you should purchase an opk and use it as directed, generally start testing ~ day 10 if you have regular periods.
