Dear all,

If A1 is equal to Mon 1300, and when I plus another 12hrs in A2, it will
become Tue 0100 in A2.

Any idea how to achieve this?

Thanks!

You need to have a date/time in A1 - for example, enter 8/01/07 13:00
in this cell and use Format | Cells | Number (tab) | Custom and set the
format as ddd hh:mm.

Then in A2 enter this formula:

=A1 + 0.5

The format should be the same as A1. Excel treats times as fractions of
a 24-hour day, which is why you need to add 0.5.

Hope this helps.

Hi Alexander

Excel stores time as fractions of a day, so 12 hours = 0.5. So in A2
=A1+0.5

If you were wanting to add times that were not as simple as that, e.g. 5
hours, then
=A1+5/24
or
=A1+TIME(5,0,0)

Thanks for the prompt reply. But this is going to be a repeated event.
Therefore, I cannot set a default timing at the very begining.

So, If I just want the add on the basis of ddd hh:mm, is that possible?

Yes, but what if I want the weekday change after time has been accumulated
over 24 hrs? Any chances?

Hallo

I have a quistion about time formats in exel too.

If I f.ex have the time 1 minut and 31 seconds (tt:mm:ss) = 0:01:31 but i
want the time only in seconds (ss) = 91.

How do I do that?

I hope you can help me!

Greetings

Format as [s].
If you want to use the number 91 in a subsequent calculation, then use the
formula =A1*24*3600 (and format as general or number, not time).

Hi Alexander

Did you try it?
The date alters as well as the time.
If you are adding more than 24 hours then
=A1+50/24 would be the same as adding 2 days and 2 hours.
