This is much more complex than you may expect.  You have to account for all kinds of corner cases (for example when the clock starts on a work day but before 9am or after 5pm etc).

Here is a sample implementation that returns the resulting day fractions.  You can multiply the sum by 24 to arrive at the hours, or leave as is and interpret as duration.

The sample implementation is a proof of concept - you would have to provide a couple more test intervals to see how this could look like in production.

Where would you like to do that, in Power Query or in DAX?  Are you aware of the NETWORKDAYS() function in DAX?

You also need to define what should happen if your interval starts or ends on a non-workday  (in your example Janary 30 is a sunday). Should the hours still count or should they be ignored?

Thanks for Picking my query:

I've got the duration in HH:MM:SS format in Power Query with below query. but unable to calculation on Matrix Visual, However it given result in Power query.

HH:MM:SS - Resolution time (hrs) New =
VAR MTTR = 'Task Acceptance P1-P2-P3-P4'[Resolution time (hrs) New]
VAR Hours = TRUNC ( MTTR )
VAR MinSec = FORMAT ( MAX ( MTTR - Hours, 0 ) / 24, ":nn:ss" )
RETURN
IF ( NOT ISBLANK ( MTTR ), Hours & MinSec )

it is taking zero in Matrix Visual.
