Open Ticket Age - Week Calculation

[JaiPrakash]

Hello Experts,
I need help for creating an Open aging incident report. I’m part of Service desk and my team lead has assigned me this task.
I have pulled raw_data of incidents from ServiceNow a ticketing tool that we use. Below is how the raw data looks. Raw data generated on 4-Aug-2017
