Create Cron Expression to run every 1 hour and 30 minutes

Hi all,

I was wondering if anyone could help me with creating a Cron expression, for a job to run every 1 hour and 30 minutes every day (MON,TUE,WED,THU,FRI).

Thanks for all the help in advance.

A strategy could be to split it onto two statements:

 0 0,3,6,9,12,15,18,21 ? * MON-FRI *
0 30 1,4,7,10,13,16,19,22 ? * MON-FRI *

@Sidney_Vogel

if you need to run for 1 hour and for 30 mins and again next job after 1 hour and 30 mins then use this

0 0,30 */2 ? * MON-FRI *

Cheers
