What is an Ovulation Calculator?

An ovulation calculator or ovulation calendar is a tool to determine the days that you are ovulating. Ovulation is when a mature egg is released from the ovary, pushed down the fallopian tube, and is made available to be fertilized. A woman is able to conceive, or is fertile only during a certain part of her monthly cycle. That period for most women is just before and during ovulation. It is no surprise then that you can increase the chances of conception by learning when you ovulate and consequently determining when you are likely to be most fertile.

Approximately every month an egg will mature within one of your ovaries. As it reaches maturity, the egg is released by the ovary where it enters the fallopian tube to make its way towards waiting for sperm and the uterus.

How does ZenParent’s Ovulation Calculator determine my ovulation days?

Our online Ovulation calendar asks you for the date of the start of your last menstrual period, and uses that to determine the days you are likely to be most fertile. Most women ovulate anywhere between Day 11 – Day 21 of their cycle, counting from the first day of the LMP. This can also be referred to as the “fertile time” of a woman’s cycle because sexual intercourse during this time increases the chance of pregnancy.

Please Note: This Ovulation Calculator tool provides approximate dates only and assume that you have a regular menstrual cycle.
