Don't forget that date-based ovulation prediction isn't perfect. If you want more precise methods you may need to use some kits, measure your basal body temperature and so on. If you want to read more on the topic, continue here.
Ovulation Predictor For Webmasters
Once downloaded the above script, unzip it and upload it somewhere in your web host. It's just one single PHP file so all you need to do is to upload it. Then put the following PHP code in your web page:
<?php require("ovulation-predictor.php"); ?>
That's all! Note that if you put the calculator in a folder, you need to give the relative path to it.
You can customize the CSS and the design by directly modifying the PHP code in the script. Some very basic PHP knowledge may be needed to avoid messing the code.
This ovulation predictor script is completely free and you can do everything you want in it. There are no obligations at all. There is a link at the bottom, but if you wish to remove it, that's ok (I will however appreciate if you leave it there as is).

This calculator is now available also as wordpress plugin. You can find it here.
