Custom Date Parameters

Hi, I have a report with calculations based on the typical calendar day. However, I've been tasked with reporting my calculations to overlap to 2 calendar days i.e. between 5pm (previous day) to 5pm (next day).

How would I approach this since all my calculations are linked to my calendar table? I know the question maybe vague so here's an example:

I have a measure that calculates the total amount of job bookings in a day and they range from 12 midnight to 11.59pm. Now I need to calculate total job bookings between 5pm (previous day) to 5pm (next day). Hope that makes sense.

Appreciate any suggestions. Thanks.
