I believe this cannot be done with the built in scheduler.

However, you can call schedule executions via API. In which case, create your bespoke app, with your own timing logic that triggers a schedule programmatically - and now you can do whatever you want.

If this is too much, perhaps put in a product suggestion.

Hi Mad Amruthur ,

There is another option, it's not ideal but it is simpler:

You can create a schedule that runs every 15 minutes, and in the master flow create a condition that checks the day of week and hour, and if the hour isn't in the range it continues to run the data flow, otherwise it just ends.

In the master flow add a conditional:

 

and in it try the PQL script:

Hour(datetime()) >=8 and Hour(datetime()) <=17
and
ConvertToNumber(dateformat(datetime(),"e")) >= 2 /*may be 1 in your case, I think it varies absed on locale*/
and
ConvertToNumber(dateformat(datetime(),"e")) <= 6

notice the day of week may vary (for me Sunday is 1, I think it may vary between environments).

 

This will run every 15 minutes, but outside of the desired schedule it will immediately terminate.
