Include days of the week in cron expression?

I have a cron expression for a schedule that runs every 25 minutes between 8am-5:59pm and I would like to add to that only on Monday through Friday but can’t for the life of me figure it out. My current expression is…

0 0/25 8-17 * * ?

0 0/25 8-17 ? * MON,TUE,WED,THU,FRI *

Thanks @vvaidya, that gives me the days of the week…the problem is when I enter the expression into the schedule it says the next time it’s scheduled to run is in 14 hours? I am on EST time here so it is 1:17 PM right now so I would expect it to run every 25 minutes up until 6PM. Am I missing something?

14 hours…Looks like your Orchestrator is in GMT time zone. You need to change it to Eastern.

That took care of it, appreciate the help!
