How do I write the formula to calculate someones time worked

[deusy]

I would like to use excel spreadsheet and calculate a simple payroll time
card. A person start time to work is 10:15 pm (cell A 1) and end time is
2am (cell B 1). What would be the formula for cell c1 to calculate the total
number of hours worked which would be 3 3/4 hours total worked. .

In order to calculate the time correctly, the cells must be a date-time
field, (especially if you are calculating times on two different days.

The formula would be (assuming start date-time is in A1 and end
date-time is in B1) :
=(B1-A1)*24

=B1-A1

if you want in time format (3:45)

=(B1-A1)*24

if you want it in decimal time format (3.75)

=MOD(B1-A1,1)

or

=B1-A1+(A1>B1)
