I would like to total lists of Hours and Minutes, adding or subtracting,
but not related to a calendar 12 or 24 hour system. The totals need to
be in hours and minutes without losing or gaining the odd minute.

For example


23479:32 plus 10010:59 minus 241:45

The result should be 33248:46

Any help would be appreciated:confused:
 
A custom format of
[h]:mm
will let you work with times up to (but not including) 10,000 hours.

Since two of the times in your example exceed that limit, your only
option is to enter your times as text and write custom functions for
addition and subtraction.

=23479/24+"0:30"

=10010/24+"0:59"

241:45

then use

=B1+B2-B3

or in one formula

=23479/24+"0:30"+10010/24+"0:59"-"241:45"

returns 33248:44
