To sum column C just use the regular function =sum(C1:C3). The cell with the
sum function change the format to a number with 2 or more decimal places.
The sum will be in days. To get hours simply multiply days by 24. To get
minutes multiply by 24 * 60.

Column C formated as h:mm

Need help with formula to sum time.

Reg [sum] I get 2:32 then *24 I get 12:48, the correct answer should be 26:32.

Thanks!
