[cron] Run CRON job everyday at specific time

Right now i am running my cron job everyday at 3.00PM

0    15    *    *    *

But I want to run my cron job twice in a day. 10.30AM and 2.30PM

0    30 10    *    *    *

I believe this command will run at 10.30AM. How should i run it in 2.30PM?

From cron manual http://man7.org/linux/man-pages/man5/crontab.5.html:

Lists are allowed. A list is a set of numbers (or ranges) separated by commas. Examples: "1,2,5,9", "0-4,8-12".

So in this case it would be:

30 10,14 * * *

you can write multiple lines in case of different minutes, for example you want to run at 10:01 AM and 2:30 PM

1 10 * * * php -f /var/www/package/index.php controller function

30 14 * * * php -f /var/www/package/index.php controller function

but the following is the best solution for running cron multiple times in a day as minutes are same, you can mention hours like 10,30 .

30 10,14 * * * php -f /var/www/package/index.php controller function
