Hi
I use jalali date,in this date 2nd month has 31 days,
but (xxxx/2/29,xxxx/2/30;xxxx/2/30) dates are not valid in the gregorian date.
how can I store these dates into TDate variables or Database fields.
I can not write english well,because it's not my native language Embarassed

The method you have chosen is incorrect. Instead, convert the date to Gregorian and then store it as TDate type.

Look at the following topic for more information:

Hmm... As far as I remember there are couple of ways to store Japanese date... There's one that's basically similar to Gregorian, just add 10000 years... hmm... wow, It has been whie since I got time to read about some of that stuff.
