How can I run command every twelve hours every day? Tried this not working :

  /12 * * * * *  mycommand

See [this](http://stackoverflow.com/a/11562834/2235132) and replace 6 by 12! — devnull, Aug 30 '13 at 05:52

0 0,12 * * * yourcommand

executes your command at 0 and at 12 o'clock.

*/12 * * * *  your command

would execute your command every 12 minutes each hour.

+1. An alternative to your first line would be `0 0/12 * * *`, using the `/12` syntax used by the OP. – glglgl Aug 30 '13 at 07:57
