Question

I have found that there is related topic.However, there are some difference because the people is asking for ubuntu server but i am using the Apache (xampp****) the latest version, so are there any method to let the system automatically send mail by checking the date ?
Can it applies to some schedule sending as well? thanks

I have the script for sending it , the only thing i need is how to schedule send.

Edit:
Make it simpler , assuming only windows is the only platform. Can i do some php script and create the cron job in os , so that my client can schedule their mail in my system instead of doing it in the os?

3 rd party cron job is good suggestion but there is limitation (what if their service break down etc…) and i want everything is based on own system

1. If your xampp is on Windows, you can use windows-schedulers to call a particular script (PHP script in your case, preferably by an URL), which checks the birthdays of all the users and sends them mail accordingly.

2. If your xampp is on Linux/Unix/etc, you can use cron-jobs, and rest is same!

3. There is also a third way, a third-party scheduler or say online-cron, which will remotely call yours script (php-page).

Example:

If you are doing the cron-settings of OS yourself, you can still let the configure as to whom to email in your system, rather than OS.

After all, a cron so is to do something repeatedly, in your case, its just calling your scripts, by an URL.

Now regarding the time settings, you can make the CRON call your script every hour, and your php script will check the appropriate time, and fire the mails!
