My bot should run from 4.30PM IST Wednesday to 1.00PM IST Thursday for every hour(every Wednesday & Thursday through out Year)..
Is possible to create single schedule. As of now we are creating on monthly basis.
Create a Calendar called Wednesday Only. Tick the Wednesday checkbox and save the Calendar. If your country has any holidays that might fall on a Wednesday, and you don't want to run on holidays, then add those holiday dates as well before saving the Calendar.
Set up your schedule to use this Calendar, and set up the schedule to kick off hourly starting at 4:30PM IST and between the hours of 4:30PM IST and 1:00PM IST.
