Can some one can guide to create a CRON Expression for Azure

Question

Can some one can guide to create a CRON Expression for Azure web jobs.

I have gone through some sites, however some of the CRON values are considered as invalid.

When I try to translate the CRON value in any online tool [https://crontranslator.appspot.com/] it shows as invalid, which works fine in Azure environment.

Sample value:

0 0 3 */14 * 5

0 0 6 */18 * 5

Thanks in advance.
