Frequently Asked Questions

The best Ovulation Calculator is Emma's Diary. Emma's Diary has been ranking number 1 for the last 125 days.

Ovulation is the process by which an egg is released from a woman's ovaries. It typically occurs in the middle of a woman's menstrual cycle, lasting for 12 to 24 hours. During ovulation, the egg travels to the uterus and provides a sperm with an opportunity to fertilize it. A successful fertilization can then result in pregnancy.


If fertilization doesn’t occur, the egg and your uterine lining will shed, resulting in menstruation.

Ovulation is not always regular, and varies from woman to woman. The simplest way to track your ovulation cycle is by using an ovulation calculator.

An ovulation calculator is a tool that helps you track your menstrual cycle.


To predict your next ovulation date, the calculator relies on data from your last menstrual cycle. It then shows a countdown to your ovulation date, which is usually about 14 days before your next period.

Ovulation calculators help you understand your fertility cycles and menstrual periods better. You can use the generated information to plan a pregnancy, prepare for your next period, or simply understand your body better.

Ovulation calculators request the date of your last period, period length, and the average length of your menstrual cycles. If you’re not sure about your regular cycle length, most calculators suggest 28 days.


Specialized calculators are also available, such as an online ovulation calculator for irregular periods, an ovulation calculator with implantation date, and more. They provide more accurate information by taking your age, weight, frequency of periods, and other factors into account.

Ovulation calculators can be categorized into:


Free Ovulation Calculators: 

These are very easy to use and can be found online. They use easily-available data to predict your fertility pattern, such as age, last period date, and the duration of your period.


Advanced Ovulation Calculators: 

For higher accuracy, an advanced ovulation calculator considers additional factors, such as your age, basal body temperature, past menstrual history, and health history.

The calculator’s accuracy depends on how often you input data into the app. See our list of the best accurate ovulation calculators and apps above.

The ovulation calculator doesn’t guarantee pregnancy. It is just an estimation of when your ovulation will happen.


There are various calculators, such as ovulation calculators for twins and ovulation calculators for gender, that promise to help you conceive your preferred gender or number of children. However, most of these claims are not backed by scientific evidence.


A calculator also cannot track your cycle accurately if you use birth control, have irregular periods, or suffer from conditions such as PCOS (polycystic ovary syndrome). It's best to consult your doctor for these concerns.
