Adding Days and Hours

[Basenji]

In an Excel 2003 spreadsheet, column D has the start date and time; D4=
4/1/09 0:01 (24 hour time). Column E has the discontinued date and time; E4=
4/7/09 15:05 (24 hour time). Column G calculates the difference and rounds
the time up or down to the closest half hour; G4= MROUND((E4-D4)1/24). Column
G is then added to give a total of the days and hours. This formula is used,
=INT(SUM(G4:G49))&†days, “&TEXT(MOD(SUM(G4:G49),1,â€hâ€)&†hoursâ€

It works fine except when the total number only has days and not any hours.
So if the total is 100 days and no hours, a “value†error is returned. If an
hour is added to the discontinue time it returns 100 days, 1 hour. How can
the formula be modified to show the zero hours when the column totals 100
days and no hours.

Thank you.

Why dont you use the custom format [h]:mm for column G. and use the normal
substraction =E1-D1 for difference and

for the total
use your formula to display in Days and hours

OR

use the SUM() function for the total..

That formula doesn't have valid syntax, so Excel wouldn't have accepted it.
Without knowing what formula you are actusally using, we don't know how you
are getting your value error, but it is usually because you are putting text
into a function which wants a number.
When you post a message here, don't try to retype the formula. Copy the
formula from Excel's formula bar and paste it in here.

The formula, when you've corrected the unmatched parentheses, works fine
even if you have a total where the hours are zero.

Here is the formula copied from the cell: =INT(SUM(G4:G49))&" days,
"&TEXT(MOD(SUM(G4:G49),1),"h")&" hours"

Where am I missing the unmatched paranthesis?

 

[Basenji]

When the sum function is used to give the sum of days and hours and the total
exceeds 31 days it returns an invalid number.

Yes, that's OK, as you've included the parenthesis which was missing from
the formula you posted last time.
That formula doesn't return a value error if you have a time where the hours
are zero.

rounds the time up or down to the closest half hour

G4= MROUND((E4-D4)1/24).

You're missing the argument separator but that's not rounding to the half
hour, it's rounding to the hour.

For the nearest half hour:

=MROUND(E4-D4,1/48)

Thank you for the clarification.

Thank you. It is working properly now.
