How to schedule the CRON to be run 1 to 1:30?

Question

I need to know cron expression to run every monday between 1 and 1:30 am.

I have tried below expressions not worked.

1 * 1-2 ? * MON *

Can anyone help me to write cron expression?

Answer 1

Try this: 0 0-30 1 ? * MON

I think, you need at least 6 slots to fill so CRON expression is valid.

Answer 2

Try the below expression

0 0-30 1 ? * MON *
