How to calculate business hours/minutes between two dates?

[hardtoguess]

I'm trying to calculate business hours between 7PM and 7AM.

For Example I have a below dataset

Start time <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">2018-01-10 19:15:00</code> and End time <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">2018-01-11 09:00:00</code>.
Start time <code style="font-style: inherit; font-variant: inherit; font-weight: inherit; margin: 0px; padding: 1px 5px; border: 0px; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">2018-01-06 11:30:00</code> and End time <code style="font-style: inherit; font-variant: inherit; font-weight: inherit; margin: 0px; padding: 1px 5px; border: 0px; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">2018-01-06 22:10:00</code>.
Start time <code style="color: rgb(36, 39, 41); font-style: inherit; font-variant: inherit; font-weight: inherit; margin: 0px; padding: 1px 5px; border: 0px; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">2018-01-07 15:30:00</code> and End time <code style="color: rgb(36, 39, 41); font-style: inherit; font-variant: inherit; font-weight: inherit; margin: 0px; padding: 1px 5px; border: 0px; font-stretch: inherit; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; vertical-align: baseline; box-sizing: inherit; background-color: rgb(239, 240, 241); white-space: pre-wrap;">2018-01-07 20:00:00</code>.


I expect calculation to return how many hours between 7PM and 7AM.
