Run every day at 1230

I can’ seem to figure out how in advanced to get the workflow to run every day at 1230 and 430 pm I thought I had 12 pm but it is showing as 830 Am
Please help here is what I am putting in advanced
0 30 12 * * ?


I would recommend just create two simple tasks one for 12:30AM and one for 4:30PM, you don’t need to use complex syntax in that case.
