This is a chart of a 28-day cycle. Notice that I have left the next period on the 29th. This is to demonstrate that counting from day 1 of your bleeding period up to and including the day of your next period is not correct. Count them for yourself and see. You should have came up with 29. This is not a 29-day cycle.

Speaking mathematically:

When you want to find the distance between two objects, you do not include both starting and ending points. You only include one or the other.

Look at this example:

You have a date on Saturday and someone asks you how many days until your date. (Imagine that today is Monday)

Answer: 5 days

Most of you probably started with Tuesday and then proceeded until Saturday. A few of you may have counted Monday and went to Friday (you still come up with the same figure though).

Now use the method of counting the starting point and the ending point:

How many days do you get now?

Answer: 6 days

By this calculation, you would miss your date because you would think that it was on Sunday.

Ovulation Calculator

This calculator will give you the approximate dates when you are fertile. It is based on a regular menstrual cycle.
When was the first day of your last menstrual period?    
Number of days in your menstrual cycle:
Here are your results:
Your ovulation date (mm/dd/yyyy) is:   
Your fertile days are:   

This calculator predicts ovulation dates based on the date of your last period and the length of your menstrual cycle. It provides approximate dates only. Having intercourse during the few days before ovulation will give you the best chance of becoming pregnant. Since sperm can survive for several days, keep in mind that these are not the only days to become pregnant.

Remember: If your periods are irregular, this calculator is not a good way to predict your ovulation dates. Speak to your doctor about other ways to help you identify when you can conceive.
