Default How to count the time?

Does anyone have any suggestions on how to count the time?
Lunch break is between 12:30 pm and 2:30 pm

Example 1
I would like to manage and know when I should start working on the task, if
I need 1 hour to finish A project, and the deadline is 3pm, therefore I
should start work on it at 12pm, 12:00 - 12:30 and 2:30 - 3:00 = 1 hour

Finish time is given at cell C3, which is 3 pm
and the required time is given in cell C6, which is 60 minutes
The starting time sould be returned in cell C2, which should be 12 pm

Example 2
I would like to manage and know when I should start working on the task, if
I need 30 minutes to finish A project, and the deadline is 2:45pm, therefore
I should start work on it at 12:15pm, 12:15 - 12:30 and 2:30 - 2:45 = 30 mins

Finish time is given at cell C3, which is 2:45 pm
and the required time is given in cell C6, which is 30 minutes
The starting time sould be returned in cell C2, which should be 12:15 pm

Does anyone have any suggestions on how to do it in Excel?
Thanks in advance for any suggestions

Default How to count the time?

Assume that you have beginning of lunch (12:30 PM) in cell A2, and end of
lunch (2:30 PM) in cell A3. Also, time duration in cell C6 is written as time
(60 minutes is inputted as 1:00 or 0:60).

Formula is:
=IF(C3-C6<A3,A2-(C3-A3),C3-C6)
